Background before my AIBU - Was at a department store earlier. Being refurbished so fewer changing rooms. There were two unattended ie no staff just help yourself changing rooms for children only. Dd had one pair of jeans to try on. Both rooms occupied so we waited and waited. One has mum and her dd trying on bridesmaids dresses - she has 6 to try on. Other one has has mum and dd trying on swimwear. Swimwear girl comes out in 6 different swimsuits to show Aunty waiting outside then mum getting her changed. Other changing room a hand appears from behind cloth so not seen anyone. After 7th swimwear ( you’re only supposed to take 3 items in) I said toswimwear mum could dd quickly pop these jeans on- shoes off ready and will be very quick. Swimwear mum says very rudely “ no I’ve got things to do and - next door have been in longer” - I said “ well I haven’t seen them come in and out we’ll be quick she has shoes off ready” . Swimwear mum says you’re spoiling a nice experience. I said well your e only supposed to take three items in. At this point get dd came to stand by mirror to look at herself AGAIN. My dd was in front putting shoes back on. I made swimwear girl wait as I tied dd laces- can’t do them yet. Swim wear mum says “she only wants a look” I said “ well she only wants to pop these on I’m just tying laces”. I left the jeans at changing room and went to pay for coat. When paying I explained to cashier what has happened. So my AIBU is - was I cheeky to ask to try on? I suffer from GAD. So just going to shops is HUGE for me. Still shaking even now.
