I have a mate who was fined for his ticket being upside down in oxford, not face down, simply oriented in a manner which the CEO took some sort of exception to.
Unfortunately he’s an argumentative and irrational individual, so rather than follow some of the sensible advice already posted on this thread, he rang them up went Batshitcrazy at them and the fine was upheald…
Send a copy of your ticket, with a polite, calmly worded letter to the effect that you had purchased a valid ticket (evidence enclosed) and placed it on display. don’t mention its orientation, or impugn the CEO’s eyesight, it won’t help your case…
