Knoebels traffic and the limited competitive gas stations. They have the the upper hand on convenience and need to pay off their newly remodeled facility.
Because people are foolish enough to pay it. If EVERYONE chose to buy gas at one station and boycotted all others and continued to do so for even 30 days every other station in that area would DRASTICALLY reduce their fuel prices.
Supply and demand. They charge what people are willing to pay. If people stop buying their gas there, they will have to drop their prices.
