Am I the only person who disagrees with this type of thing? If you can afford to sell a coffee for $2.40, then how can you get away with selling the same thing for $5, just on the basis of politeness? Also, yes, its nice to encourage manners, but if you respect your customers they’ll respect you back. If you try to effectively buy manners from them, they’ll just be bitter.
Yooooo, shut up.
*finds it ironic how someone with “socialist” in their URL disagrees with point about overcharging*
