As hinted at earlier by harru, the following event occurred on Saturday night:

Sitting at a table in a beer garden with harru. Two 'ladies' had been sitting with us, but had gone inside to get drinks. A group of approached us...

Head group person: (indicating empty seats) Excuse me, is anyone sitting there?

Me: Yes. Sorry.

[pause as person looks at empty seats, complete with empty glasses, coats etc]

Head group person: What? Really?

MeINCREDULOUS06: Yes really!

I've quite honestly never been insulted so effectively in all my days.

DiScuss, with reference to twatty double-dating thirty-somethings who think that pub seating should be decided by force majeure.
