Very rude nothing but a bully for a 50 odd year old woman

My Daughter went to a shell petrol station on ring road Sheffield to be humiliated bullied and spoke to like a dog because her card got declined for £10 the disgusting cashier refused to let her leave until paid (how can something be paid without going home for it ) my daughter phoned me absolutely heartbroken I could here the cashier in the background been rude to her and talking down to her I told my daughter to put her on the phone which she I explained to this awful woman we don't live far and she has to get to work and the reply I got was I don't care I have never ever experienced such bad customer services in my life she has no people skills . I have put a complaint in about this awful bully so see if anything is done absolutely vile manners vile people skills vile attitude shouldn't be allowed to work with public . Lucky there was a decent human being on that day who let my daughter go and told her to come in before 10.30 to pay the money I went in 1 hour later and paid this .
