There is a sandwich shop that's one of my regular places. Good sandwiches, good price. Saturday, much to my surprise, I realized the guy behind the counter, whom I've seen for over 2 years, has a very limited understanding of English. I recall one other occasion when I came in and told him something, just being conversational, he just sort of nodded his head. Now I know, he probably didn't understand a word of what I said.
It happened when a lady came in and wanted a SALAD instead of a sandwich. There are no salads on the menu. She tried to explain, just put everything on the plate with the bread on the side. She tried to say it five different ways, finally gave up and left. Hey lady, it's a SANDWICH shop - and heck, after the 2nd attempt, I realized he didn't understand what she was saying, so just give it up, right??
The same day, a tourist wandered in and asked if they had lattes. Huh? This is a sandwich shop. You order what's on the menu, you get it, it's good. Don't go gettin' fancy.
Actually, now that I think about it - I always liked seeing the guy there, because he made good sandwiches. When the relatives were there, it wasn't the same consistent quality. But in retrospect - the relatives actually speak English. One of them said "Hey - haven't seen you in awhile?" The guy never said that - and when I tried to explain to him why I hadn't been around for awhile, I just thought he was indifferent. Nope. He didn't understand what I was saying.
