I'm afraid you're right. Even as I typed my post, I was thinking that most American servers couldn't handle it. Years ago, when we still owned the condo in Vail, we started out skiing one morning and I realized I needed glove liners, since it was significantly colder than I'd expected. Next door to our development was the "Evergreen Lodge," which was really about a five story hotel, big enough to have a small accessory shop on the ground floor. I circled around, clunking along in ski boots and up to the shop, which was open. However, a morose-looking late teenager was behind the cash register. I picked out what I needed and tendered $15. He apologized that their network was down. I asked if he could open the register. He could. I suggested that I could just leave the money, take the change and leave my business card, with my phone number next door and, at the end of the day, I'd check back by and, if my purchase caused a problem, we could back it out and redo it. He replied "But I wouldn't know how much change to give you." I let that sink in for several seconds. Then I replied that I'd just leave the $15, take the $1.57, sign my name and check back at the end of the day. He brightened up at that and said that would work. I went off just shaking my head...
