No it isnt, its about people feeling entitled. It isnt so hard to ask for help at the counter, it isnt hard to wait you turn, and it isnt hard to walk out of the shop and get on with your life if a shop isnt up to your 'standards'. Walk out and get over it.
I value this site hugely for the information some people can give, I'm pretty sure the freshwater section of this site wasnt designed for people to complain about service at pet shops.
