I live within walking distance of Millenium Bank. I've been a regular customer since they opened about 5-6 years ago. When visiting the ATM today and checking into Yelp, I noticed they didn't have any pictures (such as a storefront picture) online.
So I took a picture and checked into Yelp… little did I realize I was making a mistake.
A bank employee walked out and asked if she could help me. I said "No. Why?"
"Well, we are a bank, and you're taking our picture."
I replied "I checked into Yelp, and I'm taking a picture of your storefront as a social picture" and she said nothing, but walked away.
I was standing outside, in the parking lot, taking a picture of a bank for a social media website. The Fourth Amendment and the legal test of "Reasonable Expectation of Privacy" were fully within my rights. I was taking a picture of a bank on communal property for a social website.
So while I appreciate this bank, I think their employees are a bit paranoid bordering on unpleasant. I was unsure of whether to give her my business card, show her my picture, or launch into an explanation about the benefits and worth-of-mouth of social networking sites such as Yelp.
