I wonder if we have a generation who are so used to being doused in the stuff that they haven't learned to hand wash.
More likely a generation too lazy to wash our hands at all. The sheer number of dirty buggers who don't wash their hands in public loos is almost criminal. Then you have all the people who eat unwrapped food - crisps/sandwiches/chips etc without having washed their hands first - Eurgh!
I can't say I've noticed people using hand gel until the last couple of weeks, so if anything, it's good that there's more awareness now.
Personally, I've always had one in my bag/pocket, but rarely used it as usually I try to wash my hands properly throughout the day when I can. I would only get the gel out when that wasn't possible, i.e. loo with no soap, or after being on public transport, after handling money, or touching door handles/hand rails before eating etc.
I went on a cruise a couple of years ago - there were hand gel dispensers everywhere (presumably due to risk of norovirus) - in the restaurants and bars, pool side, reception, shops, gym etc. Also good to see the public toilets had signs up telling people to wash their hands, and plenty of soap at all the sinks, so no excuse not to. It was great to see people were using the gels - usually a small queue to use them at meal times.
It's one of those things that we need to re-educate people and make it socially unacceptable to sneeze without a tissue/sleeve, or to leave the loo without washing hands etc - people need to be called out on it like with drink driving and smoking in public.
