Racial Profiling or a Quality Issue?

Scenario: At an airport in Atlanta. I have an airline ticket in hand, in queue at the gate. There's a Delta airline attendant nearby, busily accepting boarding passes. Nobody hardly speaks to her as she repetitiously scans tickets.

Me: Good afternoon!
(She scans my ticket and the machine beeps loudly.)
Airline employee: This is an exit row seat.
Me: Ok.
(She looks up to notice me and apparently notices for the first time that my skin color is brown.)
Her: Oh. Do you speak English?
Me: Um hello! I just told you good afternoon.
Her: Well you know, I have to check.

Ugh. I'd like to label this incident as unintentional racial profiling by a huge incompetent, but it happens too frequently to ignore it. This type of subtle prejudice is much more deeply rooted in popular opinion than we care to realize and often, the public in general supports it. Ignorance or lack of sensitivity is no excuse for habitual and casually applied racial bias. It's really hard not to feel slighted.

What do you think? Am I over reacting?
