It’s not really about eating the costs of doing business. A restaurant doesn’t charge you $1 at the end of your bill for washing your fork, it’s just part of the cost of serving the dish and so your Salmon Rice dish is $18 not $17.
The point is that the listed prices for services should either have these fees be built right into the price…as pretty much all businesses do…or if you’re going to put it at the end of the bill then it needs to be clearly defined per FCC.
It’s a transparency problem. Not only is your $60 cell phone bill not actually $60 but then they also don’t tell you about the additional fees very well when they tack them on at the end. It’s gotta be one or the other, not neither.
