DD is a huge Ariana Grande fan and is desparate to go to her concert. I've looked and tickets are in the region of £200 each,
for very average seats. She's under 15 so an adult would need to go too so that's £400 for a night out before we've considered transport, food & drink etc. We can't afford it. DD is sad, especially as one of her friends is going and bragging about it. She accepts it's a massive waste of money though.
AIBU to think that stars like Ariana shouldn't be charging such obscene amounts of money, especially given that her fan base is mostly young girls. I went to many concerts in my youth and know I didn't pay anything like the equivalent of £200 (1980s/90s)!
