i had a similar instance happen to me while i was shooting photos for a local club..
my gear, gripped d7000, dome diff sb900 with battery pack, sigma 15mm fisheye.
she came up to me and asked if i was the club photog and i said, "i am tonight"
then she proceeded to ask what i was shooting with, first thing she said was, "is that a d3s?"
i said no, "it's just a d7000"
she then proceed to say, "well at least you have the sb900"
at this point was when i realized the type of person she was.
she then started looking over my shoulder at pics i just took, and critiquing every lil thing.... the main thing she had to say about the pics was that the flash was lighting up a Ginger girl a lil too much! "she's white but she's not that white."
so i told her i don't bring all my flash equipment into the club because i am just going around and snapping shots of people that want their picture taken, they aren't pro-studio quality photos. (all i had with me was what i listed)
then she said, "well if you are gonna do it, you should do it right!"
this is about the time i went off on her!
"so you are saying i should bring my slaves in here and carry them around with me so i could get proper lighting in this pitch black club? No, i'm just walking around snapping shots. but thanks for your input...what do you shoot with anyways?" -me
"canon t1i" -her
"i laughed at her, and said ok thank you for your pro advice... go bug someone else with a camera now" -me
"i'm just trying to piss you off, and i see it is working!" -her
"you see me laughing right? i think you are hilarious! now go bug someone else!" -me
she walked away.
