Shocking service

I went to the iStore in Gateway to buy the Apple watch, its a very confusing set up and there were clearly not enough sales people around to assist. Whilst the queue was short there was only one person at the counter so the wait was extremely long. When I eventually got to the front the person was trying to help 2 people at once which was very frustrating. Payment was also a painful process as their credit card system was not working and the consultant complained about this in a very unprofessional and long winded manner which only added to this dismal shopping experience.Considering that this is a premium brand the level of service was extremely disappointing
