I am an intern for a small software company, due to me not having a car, i often rely on coworkers or ride sharing services to get to work.
My boss found out and approached me, saying that he would put an extra amount on my paycheck to cover for the ride-sharing expenses as well as increasing my hourly rate by a few.
This was around a week ago, my boss is often very busy and so I think he forgot.
What's the best approach to remind him? I want to be as professional as possible as I have a great deal of respect for him and I wouldn't want to overstep my position as an intern.
