SIR – I was astounded to read of the bus operators survey of just less than 2,000 people claiming 91 per cent satisfaction (T&A, July 15).

It would appear none of these people use the 610 bus route which is regularly late, particularly apparent around mid-morning and late afternoon.

As this service is due every 30 minutes, any delays make it particularly hard on older people.

Perhaps self-congratulation should be reserved for a more comprehensive survey in the future.
