DM who lives out of London is coming here soon to go to the Matisse exhibition which one of her friends said costs £18 to get into (I think her friend didn't look properly online which states the £18 first. I was puzzled it was that much so I checked today and it's actually £16.30 without the donation, but £18 with. I'm going to pay the £16.30 because I don't see the point in paying the extra - aren't I helping to pay for it indirectly with my taxes through the Department for Culture, Media & Sport?
I don't ever bother to donate dropping money at the museum, either.
