Subway complaint: racist staff

I walked in to the store to order food just for me like i sometimes do when im near that store after i seen white people go in and buy food. As i took 6 steps in 1 of the women turned round and started messing around with some wapping and said we are not taking any orders as we are busy i turned round and said i was just wanting 1 thing she said {so what]. so i said if you are not letting people order you sould not be open and walked out as i was standing at bus stop i seen both black and white people walk in but all white people was walking out with food and the black people was having to goo somewhere else i find this disgusting and therefore wish for them women to be banned from all subway store and for them to come to a place where you see fit to say sorry or something else please as nobody has the right to be racist to anybody else
