Subway

We went to Subway and experienced a very rude and racist encounter. We came for you'lls "fans who buy any sub and any drink will get a free sub of equal or lesser value on the house" deal. I agreed to buy 2 subs and 2 drinks and expected to get 2 subs for free. Then the man goes back and when he comes backs says you have to buy 4 drinks which I agree to. Then when I asked for the total it came out to be a little more than $35. This makes no sense because the subs were $6.75 each and even with the 4 drinks (which I should not have to pay) the total with tax comes out to be $23.22. I asked to at least see the breakdown of the costs but he refused to do so, saying, "I will not show you anything until you pay". He said take it or leave. So I left and upon my leaving he called me crazy. I have never in my life felt more disrespected. The man was extremely rude. My mom was with me wearing a hijab (a head scarf), and I believe this man was being specifically racist to us because the person before us bought 3 subs and got 3 free and only bought 3 drinks and his total only came out to be about $30 which is less than what my total came out to be. This is the first time in my life I have felt racism and I couldn't be more disappointed in Subway.
