It may well be that hotels, guest houses & the like are training their staff but how often than not do you see the water conservation notices in your room e.g. ‘If you want your towels washed leave them in the bath’? So you don’t do that & hang them up but yet they STILL get washed!
Secondly why do towels have to be SO BIG? You are simply drying off CLEAN water?
Do we have to wait for a crisis like we now have in Cape Town (& soon nationwide?) to be proactive?
