I just mentioned this discussion to my hub (he's really not interested but I continued trying to tell him about it anyway).

He said, ok, well when driver needs overtime I wave a bottle of HP sauce at him and say 'off you go - try and find me some of that'.

I think he meant that was his contribution to 'giving a tip' when someone else is saving him from having to scout Doha malls himself.

I guess it's better I don't involve him in QL discussions - I don't get very sensible answers :o/
