Situation: I am standing by a sink facing the wall while there is a paper towel dispenser on my right, another sink in my one o'clock direction and a bathroom stall door in my seven o'clock direction.
Alternative situations: I am walking away from the stalls. The sinks are on the right side of me. I just finished washing hands sink to my right, with my right hand pulling a paper tower from paper towel dispenser just above the sink.
Question: How many trash cans are on the right side of the wall?
