I paid for my restaurant meal and the receipt said, printed at the bottom, that 25% went to the Liquor Replacement Fund. I was puzzled by this for a while, and then a barely visible sign on the door of the restaurant gave me a clue and a hypothesis. The sign said that this was a private club and that alcohol would be served only to registered members. My guess is that this is thr remnant of a very old local liquor law, that everyone has worked around instead of changing. I speculate that by putting my name on the list for a table, I was registering as a member of the "club." And that the notice at the bottom of the receipt explained that I wasn't exactly purchasing liquor, but rather being served liquor from my private club's reserves. And that the restaurant wasn't taking a profit but rather saving the money to buy more liquor for the members.
Liquor laws can be funny. Some places in Canada you can't serve alcohol without "a meal" so in those places you can buy the most minimal meals known to man. You can collect ten bucks from a bunch of people to buy a few cases of beer, but if you then put them in the fridge with a can on top and ask people to contribute a few coins towards the next case for every beer they drink, you'll get in trouble for selling beer without a licence. At least some places. The laws can be quaint.
When I say "a few coins," I mean more money than I might if I were talking about American coins. Canada doesn't mint one or two dollar bills. We used to, years ago, but now we have one and two dollar coins instead. So when I'm working with money, looking to pay for a cup of coffee or expecting change from something, it's natural for me to go for the coin purse not the billfold for amounts under five dollars. When I first get back to Canada I'm momentarily surprised by getting a handful of coins as change from a ten for a small purchase.
The US does have one dollar coins. I got several once as change from a stamp machine. And they have two dollar bills. I decided to use them. I went to a bank in Texas with a twenty dollar bill and asked for ten ones and five twos. The teller managed to scavenge seven ones from her own and another teller's drawer, but denied having any twos in the whole bank. Well so much for that plan. I took my metal ones, and the rest in paper ones. I can get more coins from post office stamp machines.
Using the US dollar coins isn't a problem with people. The reaction is usually one of slight positive surprise and "hey cool" scrutiny of my proffered dollar. No one has refused a coin or asked me to give them a banknote instead, but I get the idea there are a few people who have never seen one. I read that when Canada introduced the loonie, our one dollar coin, they made sure to mint tonnes of the things to overwhelm the "hey cool" response that would cause people to keep the first few they met as a souvenir. Perhaps the reverse effect helped to cement the switch: people hoarded their last few dollar bills as souvenirs, hastening their withdrawal from circulation.
I can see a reason why the dollar coins might be unpopular in the US. You can't use them in vending machines. A newspaper cost a dollar. The box says "Use Any Coin Combination - Do Not Use Pennies." What the box means is "use any combination of quarters, dimes and nickels." The dollar coin shown doesn't fit in the slot.
Because the denominations of commonly circulating US coins hasn't changed in over a hundred years, but prices have, vending machines compensate in other ways. Many US vending machines accept banknotes. You unfold any bent corners and line up the picture of the president on the bill with the picture on the slot. The machine feeds in the bill, whirrrs it back and forth a couple of times and spits out your chocolate bar and a pile of quarters. If the machine doesn't take bills, there will often be a change machine nearby. There are change machines in Canada, but not as commonly, and of course they spit loonies.
