"See you tomorrow!" & "i'll come back later"

So i just wanted to post a couple of funny things....
#1- last week when i went over to my cousins so our kiddies could play, we went to McDonald's to pick up some lunch before we headed over to the park. Since we both had to drive our own cars, (car seats), i followed her through the drive-thru. when i paid for my order and picked it up, the guy in the window said "see you tomorrow!!" i thought that was pretty funny. who says "see you tomorrow!"? if anything, he should have said "see you next time" or "have a nice day".
#2- I'm covering the shop for dadi right now and a customer came in. so far when I've watched the shop, I've been pretty lucky and no one has come in. NOT TODAY!! he leaves and about 10 minutes later a customer comes in. He shows me a screw looking thingy and here's how the conversation goes......
Him: "i need a box of these"
Me: "okay, I'm watching the shop for my husband, he went out on an emergency delivery. do you know what the name of this is?" (meanwhile, I'm calling dadi on the cell phone so he can help me)
Him: "no, i don't know what it's called. it's made of sheet metal"
Me on the phone: "dadi, he doesn't know what it's called, but it looks like a bolt on top of screw and it's silver"
Dadi: "does it have a pointy end and a slot of the top?"
Me: "yes"
Him: "never mind, I'll come back later. if you don't know what it's called, and i don't know what it's called, then we'll never find it" (he starts walking to the door)
Me: "wait, i can find it"
Him: out the door and long gone....
Dadi: "ask him what he needs it for"
Me: "he left"
Dadi: "oh"

so, that was fun. i love feeling like an idiot.
i should come in a couple of times a week and get some training from dadi so i can know what things are. i don't have to watch the shop very often, but when i do, it would be nice to know a little bit about what these guys are talking about. i hate feeling like a dumb girl.
