How can people not know that they smell? I mean, I’m on the tube in the morning and the smell from some people is disgusting. There are the general BO travellers who just don’t seem to have heard of deodorant and to be fair I think they’d need to soak in fairy liquid initially to get that stench off them; then there’s the musty clothes wearers, you know the ones, where their coat smells damp, verging on stagnant; there’s the bad breath ones whom I watch wondering who their loved ones are that have to kiss them… and the stinky hair ones with grease and dandruff, I mean how bad is that, that your dry scalp managed to get greasy at the same time?! Sorry but I don’t think there is an excuse. Toiletries people, soap, use it!
