Bad service

I drove to the garage to buy energy drink and snacks but when I got there, everybody was sleeping, I tried to call for help but was ignored then I whistled so the can wake up, and I was given attitude by one of the staff members telling me I shud not whistil and I told him I tried to call for help but no one was responding and there wer also customers outside waiting for service . I was told they are making me a favor by letting me buy in the shop and I asked for the the name as the person who was giving me attitude did not have a name tag but he was not willing to give me full details. I then told him I am goin to report the matter and He told me he don't care if I do so. I will never fill my car thank at ther service station that does not care abt customers.
