YetAnotherSpartacus, really? As a middleclass white woman I experience very little prejudice and although I object to the assumptions made about old people, male and female, being racist homophobic etc I don't find it means they get treated differently in fact it is generally a get out of jail free card as it is used to excuse unacceptable behaviour.
ShatnersWig, not it wasn't in fact, I was ignored by two volunteers behind the counter. That was the most blatant example but not the only one, just the final straw. If you read through the thread I'm not the only person to experience or witness such behaviour. The NT needs to deal with it, I don't care if they are volunteers, even if they pay the NT to let them go in and show their prejudice they shouldn't be allowed to do it.
I didn't complain on the day, we were meeting friends and they had chosen the place so I didn't want to make a scene, I am quite famous in the family for being the one who speaks up and challenges this sort of thing but wasn't appropriate on the day.
