Bathroom Etiquette

So your probably thinking, "Oh my gosh, where is he going with this..". I was using a public restroom the other day and as I was performing the mission at hand, the user of the stall next to me kept distracting me with his loud snoring. Now, I wasnt sure what to do. Should I use this time to get some rest myself? Should I bang on the wall and tell him to keep it down? He eventually woke up before I could decided on a plan of action, but I really need to be prepared for the next time this happens.
