After almost finishing our shopping (we had been in store for well over an hour) my daughter spotted a dress she liked. As we had 2 of the store's shopping bags, full to the brim, and as I was extremely tired (I am 74) before we entered the dressing room I called over the queuing barriers to the assistant at the entrance asking two questions: 1. Was there somewhere inside where I could sit down while my daughter tried on the dress and 2. Were we allowed to bring the 2 shopping bags into the dressing room. We received a very surly answer of "yes" to both of the questions. We therefore made our way down the queuing barriers to the entrance.   My daughter was asked how many items she had to which she replied "one".  The woman then looked at the 2 shopping bags and said, again very abrupt and surly "you can't take them in, you'll have to leave them here" even though I had just asked asked her and the answer was yes we could. I proceeded to put the bags in the back room to which I was instructed to "take them out and put them here", "here" being right in the entrance to the dressing room. I pointed out that someone would fall over them to which she replied "you need a ticket". The ticket was duly given and then I had to pick them up and place them, yes, guess where, back in the backroom. Why they couldn't have stayed there in the first place whilst I was given the ticket is anyone's guess. My daughter tried the dress but it was too small. At the exit a different lady put my daughter's "how many items" ticket into the machine and said "you took 5 items in".  My daughter said "no, I only took one item in". The assistants then kept shouting through to the surly woman at the entrance who said "she hadn't written it down" whatever that meant. What followed was excruciatingly embarrassing for my daughter. She was literally frog marched back into the dressing room by another assistant who looked round the dressing room with my daughter and then in front of a now, very long queue, shouted loudly that there was nothing in there. The whole fiasco was horrendous. The "frogmarching" assistant then apologised to which I replied that the assistant on the entrance needed training on her customer service skills and her manners. I was then told it would be reported to the Supervisor. I spent £165.50 and my daughter spend £102.00. If we hadn't spent such a long time choosing the gifts I would have just walked out without buying anything. The time was circa 1.00 pm on Wednesday 13th November. It was a really bad experience and we both feel really aggrieved.
