I have been asked quite regularly if I need help and it always puts a smile on my face
If someone looks lost or in trouble I will ask. Last week a guy looked really lost, he was standing looking at direction signs all perplexed and I asked if he needed directions? His, rather rude, response was finished with 'I cycle 190 miles a week you know' and launched into a tirade of how awesome he is on two wheels. Sorry mate, couldn't really give a flying duck and I left. Puts me off helping when people can be rude in response.
