you can't be riding on someone ass... you gotta wait for them to move down before you go.
its like your online at a store. someones checking out and your next. They can't check out two people at once (riding on their ass). so when the person up is done, as im waiting for them to grab their bags and put their money away, you walk right up because you think im not going and snake my spot
its respect man, i try to give people their space to go, and get really mad when people cut me off, there for i wouldnt cut people off myself
