They wanted to "sticker" my case. I asked why. They said "are you returning it?"
"No, it's my car stereo." "Well, what are you doing?" "(deadpan)Going shopping?" "(dumb look)" "Well, do you need to sticker it?" "No."
No one asked me anything, and I left without incident.
I hate Wal-Mart.
Anyhow, the only 2 times I've needed to open the case were in a craft store (where they apparently sold such cases) and when I tripped the alarm at Best Buy (they hadn't deactivated the security tag on what I bought).
