Unprofessional behavior

Sunday afternoon(06/07/2015) went to buy groceries at Game in N1 City (Goodwood) they lady that assisted us at the till had to call a Supervisor to authorize a purchase/price for one of the item we bought, we waited for more than 20 minutes for that,She then came and assisted people at the till next to us and left, we had wait once again for her , we then out of frustration called her name and that's the only she came to shouting that what we doing inappropriate, We then told her we have being waiting fr over 30 minutes now and the she said We are not the only customers in the shop that she is helping instead of apologizing for making us wait long with not response or an alert that she is coming she gave us attitude and left without apologizing.<br> <br> 1. If she was so busy why did she only come when we called her name.<br> 2. Were we not that important to her to tell us that she is at least she is coming.<br> 3. Why did she help people who got there after us?<br> 4. Why did she not listen to the query first before answering us ?<br> 5. How long must one wait to just get one item authorized?<br> 6. Is back-chatting to customers allowed <br> <br>
