How hard can it be? Check this out:
Me: Do you have size 42?
Shopkeeper: Wait let me check.
The shopkeeper goes to the cashier and they start f***ing around with the PC.

Me (thinking): Bastard
Me: OK. How about 43? Maybe it will fit.
I turn my back to look for something else.
Shopkeeper: But we have size 44.
Me: I am not buying a boat here am I?
