Easy and Ryanair have three toilets for 180 passengers on A320/B737. It makes a difference on a flight if you are hanging around waiting for the toilet and disturbs passengers seated near the toilets..
I regularly SLF on Aeroflot's A321s and they have 3 lavs for economy. 2 in the middle and one at the back.
