I know how that feels.

Me too. Ive done it at Starbucks Lol. Embarrassingg. I always leave the tip after I get my change back.

Learn to read prices. ???

been there done that

Honestly, YDI because you need to pay more attention to the prices of what you're going to eat.

Agreed, especially if you're going to a restaurant, tax isn't hard to estimate and you should probably make sure you have a couple dollars extra. FYL for having to pull out the tip but YDI for going to a restaurant and not checking prices and your wallet.

While it is silly to throw in a tip before you pay (the service isn't finished yet). 

I can only excuse OP for some places only advertise prices without Tax, making it sometimes a bit guessing what the price would be in the end.

Lol why would you tip before you paid for your bill and second why would you tip at a fast food place .

he never said it was a fast food place dummy

yeah, idiot..where did you get that idea?

azeem is too poor to go to actual restaurants so fast food is a he knows

I've never been to a fast food where you eat first and pay after. So I'm pretty sure it's sensible to say it wasn't fast food.

Which fast food would allow you to pay after your meal?
Obviously not a fast food place as they be out of business fast.

You should always tip after you've paid.

yes alwayys

Yeah...next time wait until you get your bill before you leave a tip! YDI, sorry.

And that's why you tip AFTER you pay. :3

this man's a genius

Pay more attention to prices? YDI... but FYL for the glares and black marks you probably got for taking back your tip. ...wait, no. YDI, period. Edit: Hey, cool, #8.

Lol, you look like a cheap bastard. I hate it when that happens.

Haha, YDI for not making sure you had enough money to tip in the first place.

Dude, that is so embarrassing. I hate when I don't leave a tip after good service, and have to explain to them that I have no money. So embarrassing. You must never have been broke before
