Tom Thumb review: Could not get change for air pump at gas station, cashier rude

on July 15th a Thursday I visited Tom Thumb in Dallas Tx. at 8698 Skillman st. at 12:20 midday. I was at the gasoline station attempting to put some air in my bike, I tried my debit card and would not take so I attempted to get 2 dollars in quarters from the attendant. I am 67 years old and am a bit hard of hearing and with the attendant behind a thick glass it was hard to understand him, he had another customer before me and he seems to enjoy talking to customers because he took a couple of minutes speaking to that person while I patiently waited. When it was my turn I asked for change, he seemed to be trying to make conversation with me and I could not fully hear him, so I repeated my request and explained I needed it for the air pump. He continued talking but now he seemed a bit agitated and disturbed (I could see it in his face) with me so I repeated my request, meanwhile a car drove up to the air pump and that person put money in the pump and the cashier said I should get in line with her and ask her for some air if she did not use it all. I did get in line behind her and explained to her I needed some air too, I ended up helping her put air in her tire. The cashier has to realize that some of us senior citizens just need to do out daily chores and be done with it. All I wanted is some change so I can be on my way.. If I offended him in any way, by not making conversation with him, I do sincerely apologize, just explain to him not all people are as chatty as him and with the thick glass and my old man ears it was not the best time to converse.
