I suspect that those drunk cyclist you see wobbling back from the pub would ride like that sober.
My favourite pub (The Fat Cat, Nelson St, Norwich, Norfolk) has a bike stand for its customers. Another Norwich pub had a bike stand installed as a memorial to a cyclist/real ale drinker who recently passed away.
The cycle campaign group and real ale society seem to be interchangeable.
Ive seen one pub in London, frequented by couriers, which had a few score courier bikes locked up on multi-story rails around the pub.
Even the UKs foremost petrol-head idealogically-unsound car reviewer rides back from the pub by bike.
Riding whilst off your face on any mind-altering substance is just stupid as well as illegal.
