you're welcome but no thank-you

[machadinho]

Hi. Suppose you do me a favor but I show no sign of gratitude whatsoever.
What could you say to let me know that you expected a thank-you?
Does an unprompted you're welcome work?

Thanks!

Hullo Machadinho. This is where sarcasm is at its most useful ~ say whatever you'd normally say in response to Thankyou, but in a tone of sarcasm [words in bold get the heaviest sarcastic stress]:
Oh you're welcome
No no, don't mention it
It was a pleasure to help
No really, think nothing of it
...

Unless you want to be actively insulting, of course.

Perfect! Thanks!

'No bother, any time(!)' is another one.

Great! Thanks! I've to practice the intonation though.
