Dissatisfied Customer

I purchased some goods and went to the "Queue" and the Sales Lady 80499 had just finished serving a customer , I was next in line so I approached the till and placed goods on the counter she said she just wanted to help one of her colleagues and left we waiting, never said that it was a cash only till and not interested in servicing me. Eventually another sales assistant told me I should be in the queue and the till I was at was a cash only till and that .... he carried on serving a new customer. (The Sales Lady 80499 never mentioned that to me in the first place) Eventually Sales Lady 80499 told me to go to another till and rang up the purchase. If this is the wonderful service we should expect form your Sales team, it is very sad.
