I was discriminated against!

I have a SERVICE DOG , he wears his Service Vest- I walked into Gateway to purchase a Cola and the Manager demanded to know my disability and that I PROVE that my Service Animal was really a Service Dog!! She said it was the rules Because of Subway!! She continually repeated over and over "I Have to see papers!" I tried to tell her I was Disabled and he was a Service Dog- she screamed at me and said ANYONE CAN SAY THAT! I told her it was a federal law she could nt ask me Questions about my duisability- I was so upset I left the store and told her to "stick the soda!" I told her I would call the owner and She leared at me grinning and said go ahead wont do any good!
I have a hard time understanding the ignorance of people who claim to be managers- not knowing the Laws! I have submitted a Class 3 complaint to the ADA. When they finish I am filing a Civil Law suit- Its my right as a Disabled American Citizen!

Oh My Gosh!
I cant believe this. How sad . That gas station is in Duchesne, I am glad you reported them.
