I ate sandwich finished my drink and there was a big floating at the bottom. Holding back me vomiting in front of anyone I confronted the girl at the front she giggled(my guess nervousness) walked away and an older gentleman came by and just kind of looked at me like I had 3 heads I told him what happens and he threw away the cup and asked if I wanted another one. I won't be coming back here I didn't get a sorry or can I refund you your money, I had to pull over, threw up my whole sub just thinking about it and won't touch the steak fries I took to go because of how my stomach felt. Worst $15 I have spent at any place. BTW, customer service goes a really long way.
