To answer Sable Knight's original question - If somebody was rude to him/her, the appropriate course to take would be to write/phone and make their comments known to the company managers in order that measures may be taken to prevent recurrence: This would be the course you would take in any such situation in any industry. As to whether it is worth it, nobody can answer that except Sable Knight - in truth, I suspect that the original question was rhetorical.
Could we all try and move on now that the question has been answered?
