Many thanks to both pthalo and Spring. It all makes sense now, I see 'li' in a more positive light, before it was a nuisance
I would never ask a tax driver for a receipt if I was travelling privately, that would be ridiculous lol But when travelling for business one has to produce receipts of all the expenses, or else the boss will not be happy :P Thanks Spring for going into the trouble of looking up the rules for me
(I would give some thanks, but I can't see the buttons)
