Disgusting customer service

I drove in into this filling station around 10:30 This morning 20/08/2019 at pump 4 to fill up diesel. Then this attendant came to my my window and said absolutely nothing just stood there. No greeting not even a **** smile. I gave him a key asked him to feel my tank. When he's done he comes again hangs on my window with an attitude again asking for my ODO meter readings I then switch on my ignition and showed him the readings. Then he said he doenst need those readings he can process the payment without them. I them confronted him about his attitude he said he doesn't care even if I don't come back to feel up there I don't pay his salary.

If this the kind of attitude he gives customers I believe that he is in the wrong field.
