I recall a certain booking clerk in the early 1980s at Peterborough being berated by a person waiting to pick up a traveller from Glasgow, who was travelling on that notoriously difficult service to Harwich Parkeston Quay then known as 'The European'.
The waiting gent was incredibly rude and aggressively demanding to know 'Why is this bloody train 10 minutes late?' for the umpteenth time. The travel centre clerk and all those waiting for tickets & information were getting more annoyed as everyone had given this chap all the information that was available and he kept barging past the queue to enquire again. The train had left Nottingham 13 minutes late and was expected 10 late at Peterborough.
Eventually said gent shouted 'I want to know the exact reason it is late right now!'.
The harassed clerk replied 'I'm sorry sir, I don't know what exactly caused the delay, but I am told it has gained a little time and should be here in a few minutes'. This wasn't good enough for the complainant, who continued his rant about 'lousy service, lousy staff etc.'
He was interrupted by a chap in the queue not far from me who stepped forward and asked of the gent 'Do us a favour mate, if you left Glasgow at 11 o'clock this morning in your car, can you tell me within 10 minutes exactly what time you'd get here?' The complainant said 'Well obviously not exactly no, traffic is different, why?' to which the man from the queue replied 'No, but you expect this fellow to be able to and that train driver's got to stop a dozen times to pick up 600 or 700 people including a few ar*@!!%s like you !'
Said gent never did complain further.
