This really enrages me too.
If I want a fecking lukewarm beer I'll nip into Asda and pay 39p for it. If I'm paying £4 for it can you fecking well chill it please.
I don't want it unless it has condensation on the outside.
And at my age I don't care how many vacuous bar staff I piss off.
BRING ME A COLD ONE!
