There is a single track bridge at Haslar in Gosport, and it is advisable to take the primary as there are often cyclists comingthe other way and a narrow central part.
One morning, I was in a bad mood when the muppet behind started tooting and ranting.
AS I was doing nothing wrong, I stopped the Trike, and checked that he was not being courteous and checked my lights, panniers etc. and shrugged my shoulders
Of course by this time lights have changed and traffic hes come up form the other side leaving my "friend" face to face with a bus and half a dozen cars.
Simply walk the trike past the obstruction he is now causing with a polite wave..... sorted!
