Let's take the scenic route..

[InSearchOfSunset]

Time: 430am ... (half hour before i'm off.. so close to a good shift.. yet so not happening)
c.p- crazy person
me-.. me...
c.p: small coffee with 4 creamers on the side
me: sorry sir we don't use creamers at this location. It's a cream dispenser
c.p : fine make it 2 cream 2 sugar
*hands him coffee*
c.p: Tell me, what is your obligation to your customers at 430 in the morning?
me:..errr i'm....sorry?
c.p: I said what is your obligation to your customers in the morning?
me: I'm afraid I don't know what you mean sir
c.p: I mean that you didn't give me my damn receipt!!!!
me: sorry sir here you go *hands receipt*
c.p: Aren't you going to tell me to have a nice day??!?!?!?!?!!??!
me: *one slow even breath* ..no..
at which point I went and busied myself with some random cleaning in the back area where I could not be seen. Seriously.. is it all that hard to ask for a receipt? I guess I should note that we don't usually issue receipts for drink items or small stuff under $1.50

c.p: Tell me, what is your obligation to your customers at 430 in the morning?

My obligation to customers is to be here. I achieved that, goodbye!

[Voldine]

Amen!

Where I work, we do not automatically print them except on credit/debit transactions, so if a customer ever begins to act flustered about it I simply let them know that it simply doesn't happen automatically since we're a small convenience store.

[Slytovhand]

Well retorted!

A receipt for 1 coffee??? I've got to ask, how on earth is that going to be a tax deduction... well, a legitimate one?

me: *one slow even breath* ..no..

If you need to be told to have a nice day, you really need to learn some initiative.

Right about the legitimate one. Even if that is for work-related travel, the allowable amount is a pittance.

He was playing "Guess What I'm Thinking!"

It's a very annoying game.

Amen!

We're the same way at my store. Usually the customers will just stand there staring at you without saying a word, even if I've moved on to the next customers. It's really creepy! I finally have to ask them if they need anything else and then they get all huffy and demand a receipt! They should know that Jedi mind tricks don't work with retail workers!

It's a very annoying game.

But that doesn't stop people from playing it.

Tax deductions aren't the only thing you use a receipt for.....

[Supermarket Slave Girl]

My obligation would be to my bed cause i'd be at home sleeping.

Sorry you had to put up with that, especially at the crack of dawn.

Maybe I don't feel like having a nice day! Maybe I've had 63 nice days in a row, and by God I'm ready for a crappy day! Let them wish me a crappy day! "Have a crappy day!" That's no problem at all! All you have to do is get up some mornings!

God I miss George Carlin.

Right-oh! After all, you'll need it if you want to return that coffee, some two weeks from now.
(But you HAVE to take it back! I got a RECEIPT!)

[RootedPhoenix]

The OP's SC was out of his mind. I mean, it's all very well and good to want your receipt (some use it to keep track of spending), but demanding it is just uncalled for.

I love George Carlin. Miss him too.

Are you thinking of that scene in Demolition Man where Sylvester Stallone is collecting demerit tickets? (Highlight below for spoiler.)

Stallone cusses at the demerit ticket dispensor to collect a lot of tickets because toilet paper is not used in the future. They have futuristic means of cleaning themselves that he doesn't like.
