bad service

On the 7 September 2023 I went to Checkers Windermeer I did my shopping and went to the till to pay, the cashier was not so friendly and advised me that he could not help me and that it is only for pensioners, I said to him it is ok my friend is a pensioner, also ask him why is there, not a sign showing it is only for pensioners he, turned around and ask the cashier next to him to give him the sign, the sign showed that he is only doing payout to pensioners, so I left that till and went to the one next to him after we paid and I looked back I saw him help someone that was not a pensioner. for a cashier, he needs to get some training to talk to clients.
