Crying Poverty

AIBU to be cross with people who cry poverty despite having plenty of dosh in the bank? I appreciate that the amount of money we need is very individual and some need more of a cushion than others. However, a friend told me in confidence she had a large inheritance from her DF but said she 'wouldn't dream of breaking into it'. When we go out as a group the others think she is strapped for cash , and we are constantly dividing up her share of meals etc and paying for her . Another friend has two DS's who were each left £350,000,( again I was told in confidence). She is always saying how well her DS's have done financially without help. It does grate a bit !
