People often give me funny looks when I gawk cars, as 95% of the time the cars I'm gawking at are not something anyone else would consider special! In fact they are often rusted clunky old junkers that I am only looking at becuase they are rare.
One bad experience I had was at the local taxi garage. I had drove into the lot where the cabs are parked to take pictures out the window of my car. I had been sitting there for a couple minutes when a lady yelled at me from inside the building
"Excuse me, can I help you?"
I yelled back, "no I'm just taking pictures"
"what?"
"I like taxis!"
"....okay"
she was obviously confused
