I hate Wallgreens also!!! I tried to print one of my wedding pictures there one time that my sister in law took (having full permission since she gave them to me) and they refused to print it for me saying it looked to much like a professional photographer took it
I vowed I would never go back!!!
I have my images printed at Rite Aide now. They have young kids working the photo desk and they usually don't even bother looking at the pics.
