Charges for using credit cards?

[TheMalcolmConnection]

Just started noticing this around town, a TON of small businesses here are now charging 5% to USE a credit card. Many of the gas stations also don't tell you, but the price increases after you put your card in. Is this something I'm just now noticing?

I rarely have cash and I understand that it costs the businesses money to have a machine, but sometimes you just have to get with modern times.
