Thank you for the grammar

Has anyone else thought it sounds weird how so many stores say "Thank you for shopping [store]"? I've always thought it needs an "at" in there! Clearly, whoever designed this decor agreed with me for once, using the full, wordy text for the thank you sign. I also appreciate when stores have a placename somewhere, so I don't have to make one up myself.

Off to the left, the weird placement of the Guest Services signs can be seen a little bit better. It would have made much more sense if they had shifted the wall sign over to the right a bit...
