Sometimes as a server We have this unfortunate curse of trying to be friendly and getting our foot stuck in our mouth. Either you say something without realization or you just...blurt something out. I have two stories, each being an example of these.

Story 1: The Awkward Moment
On a Saturday night I had table 1 want to pay for table 2's ticket. I went to table 2 and said, "That table over there wants to pay for your ticket, it's your lucky day!"
The man looked at me, gingerly placed his hand on my arm and said, "Miss. We buried my brother today."
Oh man.

Story 2: Verbal Diarrhea; The blurt out.
I had a guy keep asking me where my heritage was from. The WHOLE time. As it grew annoying, I started ignoring him and talking more to his fellow meal-mates. He kept saying things like,
"So are you egyptian?"
"No."
"What about Italian? Persian?" Greek?"
"No. No. And no."
"Oh I know! Are you Jewish? You look Jewish."
As I got angry the words left my mouth before I could filter them
"Well are you stupid? Because you look stupid."
He didn't leave me a tip. though his buddies all left a GREAT one.

So I'm usually a very very congenial and wonderful customer. Having to deal with idiots all day who are the pickiest eaters in the world makes me a wonderful patient patron to all restaurants. But recently I had to deal with a completely idiotic server.
One of my best friends, Cecilia, and I went to a little adorable cafe specializing in pies. We were really looking forward to eating pie, but knew since we hadn't eaten anything all day, we should probably get something solid. Cecilia ordered Mozerella Sticks and I ordered a plate of Garlic Cheese Bread. Well I ate about half my bread and told the waitress I was ready for my pie. She looked at me disapprovingly. I sat there. She finally spoke.
"Ma'am I'm not bringing you your pie until you finish your food."
"Excuse me?"
"You need to finish your meal first."
"I came in for pie. I want pie."
"Well you can't just waste all that food."
"I can if I pay for it."
"No. I won't bring you pie until you finish you're meal."
We continued to argue for about five minutes until out of frustration I yelled, "Okay. Look. Get me your manager NOW!" She stared at me...well...glared at me and very angrily stormed off. About two minutes later she brought me my pie.

I didn't quite know how I should act after that. No wonder customers go to a restaurant with the idea that their servers are out to make their day worst. Mine was! At least I got my pie.
