back in 5mins while kissing

I arrived at 16:48 only to find a back in 5mins board and the guy working inside kissing his girlfriend in front of the door. When he saw me he open and said we are closed, As far as I know oasis is only closing at 17:00 and that I want my water, he eventually gave me my water after give me a mouth full of **** and saying he doesn't care and I could contact anyone whom I want because he doesn't care he is in charge of the shop. He said he has cashed up and that he has to do so every day at 16H50. If that was true why would he still give my water and why was the 5mins board up and him standing kissing his girl if he was suppose to cash up? I've been buying water here every week for 3years and this is the worst service ever!! This shop will never see me again and I will spread the word that an young arrogant male is working there and its much better to buy water from sasol or spar or anywhere in that case.
