"Nappie" is the British word for diaper. I think he/she must suffer from projection ;)
As for the A-hole from way back when, I think he harrassed waitresses in any establishment he went to. Chain restaurants let patrons get away with ALOT. I remember his wife saying "I remember you.....not what did my husband do to you? Oh, he BIT you! bawhahaha". That made me think it was his normal behavior. And all before he bit my arm, he was a huge PITA. Back then, Red Lobster was total fast food - get 'em in, get 'em out...unless they were drinking.
Oh, I use "nappie" myself for diaper, lol, so I got that. I just had absolutely no idea why he thinks I needed a box of 'em, since I couldn't find a previous post by him...and definitely not one to me. Oh well. If he cares to explain himself, he will. If not, I'll just ignore him...I'm not wasting keystrokes on someone like that. :)
As for the jerk and his wife...I suppose you are right about some chains. I know my husband has zero qualms about telling a customer when he/she gets out of line that they are perfectly free to take their business elsewhere...most of them back down really quickly and straighten out when they realize he means it. It doesn't hurt that the management will back him up...he rarely has a problem he can't solve, so they know if he's had to go there, that he's right about telling them to buzz off.
Course, he's 6'2 and 200lbs, and a former Marine so he doesn't get a lot of people that try to get in his face, customers OR co-workers. LOL!
