Good customer service

I was at Eastgate superdry on Thursday and the was only one guy in the store which was so helpful but at the same time he was watching the floor while trying to help me so I decided to go and told him I will be back so he can be on the floor which I did after 2 hours and still he was alone and I wanted to pay with pay just now and he didn't know how to use it but tried to help me even called the manager who was off on that day to assist since the manager's assist was out for more than 2 hours how can this guy leave a new person in the store alone for so long he's not serious about his job that new guy tried his best to help everyone who was there even while he was stressing but he kept his cool and someone from Diesel store had to come and assist him with pay just now please guys that assist manager is not serious about his job find someone who will work with the new guy and please give him more training his willing to work it's just he needs more training big ups to him I forgot his name but I'm sure the manager knows who I'm talking about.
