There's people like this everywhere you go. Self centered and selfish. They could care less that they are holding up 10 people+ behind them.
Heck an elderly gentleman stopped to pull over (where there is no shoulder) in the right lane of a 4 lane throughway, which is the only way into the city where I live, so you can imagine how busy that throughway is, so that he could drop off his passenger.
I couldn't believe it and honked as I got around him. My wife was telling me "to calm down and be nice because he was old. IMO, Elderly or Not...it doesn't give you the right to stop anywhere you dam please because it's convenient for you to do so.
He was holding up at least 10 other cars behind me, not to mention creating a situation for an accident.
I feel you.
