1. It's not $1. It's $1 per package to countless customers who might not be aware they are being ripped off.
2. If there's no rule violation, there's nothing to be concerned about if UPS is informed.
FYI: I don't have any connections with any of these stores.
I disagree with your first point because that is not your way of like. I promise you don't care about ploni getting ripped off, you care about your own $1. If your really cared you can do one of 2 things.
1. Go over to the owner. 2. Hang up a sign that drop off's should be free.
With point number 2. What will happen if they are allowed and since you called them t report something wrong it will hurt their relation with UPS. Just maybe?
My point is that you can't jump when it comes to someone else's parnasa.
Lets take out one more point, if you are wrong and they DO get shut down, I am not mekane your gehenim.
