Well how much do you think they make a gallon?
$1 candy bar won’t, but you’re missing the point of getting mad at a company over their profit margin. You’re really going to get mad at a house builder that he wants $300,000 for a house when it costs him $270,000 to make? 10% is a baby profit margin, yet you’re the type to sit here and say “Look at him making $300K” by looking at the gross not net.
If you really don’t like oil companies and their prices, do it yourself and buy yourself a diesel.
If you’re not willing to put all that work into getting your own gas and you want others to do that for ya, then sit down and stay quiet.
