Night Hawk, regarding the layaway issue, since you know they do offer that option, call them up and ask what the layaway requirements are and be sure to note the salesman's name. Then go in person to put the money down. If you get any flack in person, call them out then leave.

I understand the fact they have the right to pick and choose customers, but it ain't gonna kill them to be unbiased and not prejudiced to treat someone of questionable appearance like a normal person. I go out of my way to be kind to people that turn me off for various reasons, and I'm not doing it for work or financial gain.

I'd only go back to that store if they have something you want that is hard to find elsewhere. Then set the layaway trap by calling first.
