Had some welding done the other day and the lad said 'just give us a drink' when asked how much I owed.
So in the view of the assembled multitude, how much is that?
A fiver would buy most drinks. A tenner a reasonable bottle of wine. Twenty quid might cover an evenings drinking in a pub. And buy enough in a supermarket to get even an alcoholic paralytic.
I'd been quoted 35 quid by a firm that let me down so I made it 20. For less than ten minutes work.
