If you own a pet store, would you let visitors take photos of your pets?

Back in the UK I had my own pet store for nearly 20 years before selling up and moving here. Although I sold a full range pet foods,medications, and equipement, I specialised in aquatics. Freshwater tropical,coldwater and marine fish.
Customers would often ask if they could photograph tanks or specific pond fish,especially koi. Many wanted pictures of one of the display showtanks dotted around the fish room. I never had a problem with it, it was good customer relations and more often than not the photo was used when they tried to emmulate one of the tanks at home. I considered that to be a big compliment.
