No one bothers to ask for the letters anyway. I go in, do my thing and no one cares. Occasionally an employee might ask but they are familiar with the process. They smile and leave me to take my picts.
I've done revealed shops without an LOA. (I think once because I actually forgot to print it...!) It was a bit uncomfortable, though I wasn't questioned. These days, I'd prefer to have all my ducks in a row if I'm asked for documentation.
