Exxon Service Station

I just had the unfortunate experience to have to deal with the worlds worst and rudest cashier. i had two flat tires after running over a bunch of nails, and went into the store to get change to buy $1 of air. this person, Joy, told me i had to buy something to get change. i told her i had two flat tires, needed air to get home, and needed change to buy their air. she was on a personal phone call and just blew me off. when i asked again to please give me change, she told the person on the phone "don't worry, I got this " and said she can't open the register unless i buy something. i told here i needed air, and needed change to buy the air. at this point, i got upset and said i need help, i need change to get the air which costs $1, and it only takes change, and i know, as a manager that you can open the register and get me 4 quarters and 4 dollars for my $5 bill. she told me i need to leave. that's when i told her, "in this country, we help people out, and if i were in your shoes i would give $1 out of my own pocket if someone was stuck and in need. i walked out, but after looking at my two flat tires went back in and saw lighters on the counter, i put $5 on the counter and said i am willing to forget what just happened, could i buy this lighter, and get 4 quarters back so i could buy some air. she told me she "refused to serve me" and i had to go. At this point i told her i was leaving, and would never have an employee work for me like her, and that i would complain and NEVER EVER purchase another item from Food Mart or Exxon. i went to the next gas station down the street and the person was more than happy to give me change and help me out.
