Interesting Situation at the Ticket Counter...

Interesting Situation at the Ticket Counter... So I live in Jersey, but I go to school in Manhattan. I dorm there and come home every weekend or so so I'm on the train often. This morning I had an emotionally conflicted situation. Without even asking me or asking for any ID, the ticket vending person gave me the disabled rate for my ticket. I always pay full price, as I feel like me getting a disabled rate would be gaming the system to the max. On one hand I'm offended that she'd assume me disabled, on the other hand she saved me 6.50. What would you do?
