rather than leap to conspiracy theories- do you have a fasination for pigeonholling poeple before asking questions?
I have two showers a day - just because I can. Before the times of showers I use to have one bath. And the bath is not filled up half way. No one I know filled their bath up to the top everyday, as you see on the TV. Waste of time.
I was curious to the amount of water I use. and put the plug in my bath before having a shower. I did leave the water running before putting the plug in so that I am not staning in cold water while I undressed and get myself ready. Only when before I get in the shower I put the plug in and I have a shower for around 10-15mins. The water level is around half the bath. The my housemate, takes at least 30mins in the shower. I presume she takes longer.
So before mouting off and calling people names, maybe next time you can question the reason why other people have come to the conclusion they have done. Just cus your a student, doesnt mean you know everything.
