Trains and Planes
I very much sympathize with the experiences described.
However, before leaping into top Jingoistic form, thread readers might want to look at the on-line interface for booking railway tickets in the UK.
Yes.... you have to have a UK address on your credit card in order to use the web. However, you don't find this out until you have already gone through all the data entry windows and are at the last, payment step.
The only option that works is to let your fingers do the walking and use the land line.
The agent answering your call will commiserate with you and confirm that this "happens all the time" and that they "are thinking of changing it".
I'm not holding my breath ........
