Looking back in the years, I remember a client coming in to the shop and wanting to know about flights to tri city in the USA. No internet them days, ploughing through ABC flight guides, looking at maps of the USA all to no avail, we pumped the client for more information it transpired it was a town on the border of three states and the locals called it tri city.

Top spot must go to the clients who complain about food to find they were on a self catering holiday.
