I have done several of these as well. First one, the clerk was so hostile that even other customers intervened on my behalf! But next time at that same location, she was nice, and asked (curiously) what I wanted the info for. I said I don't know, I was just told to get it. Third time as this location, another clerk didn't know what to do, but this clerk walked by and recognized me, and beamed happily that she knew what to do, and helped out, even with the photo! Like old friends!
At another location, the clerk got very hostile and demanded my personal data, and demanded to know what I was doing. As patiently and nicely as I could, I explained about 10 times that I just needed to information to compare costs for sending money, and that I was fully aware it was not necessary to enter my data to get that information, and "can you please just give me the rates?". She tried to bully / stare me down, but I pointed out that I was not doing anything illegal, and I stared her back down (with a smile). Finally she caved and unhappily gave me the info. I did not attempt to ask her for a photo!
I decided that next time I will say I am gathering info for sending money to charities in other countries and want to evaluate the best price before making a choice. Or that we are watching trends in the marketplace to decide the best time to send money (my spouse is from another country, and has actually done exactly that for his home country, with banks).
It is legit, the clerks just don't know anything, so they are suspicious. I do keep mentioning that "one time they used something called 'an estimate key'?, and did not need to put in any personal information".
It's such an easy shop, if you can get past the suspicious/ clueless clerks! Also, they tend to mix up the W2W and regular services, so I often have to double check (and discover that they told me WRONG), which annoys them to no end. Sometimes I even have to tell them *where* on their screen to look for the information - "if you look in the column all the way to the right, it should say ... "
