A friend asked me along to a spa day. Her and her husband are very well off (they work hard, don't begrudge them that at all) but have a bit of a reputation for being tight fisted (always last to the bar etc). It was quite expensive but I thought a nice treat. We came to pay and she said she'd cleared it already and I just owed her for mine as she had a voucher for hers. If it had been me I would have said up front I had a voucher and needed someone to go with and I would have shared the voucher. I didn't necessarily expect her to do that but I think she should have said something before booking. I can be over sensitive so I accept this might be the case here but this is a long line of similar situations. Not an earth shattering problem I know!
