you jump through hoops if you try and claim without a
ticket.

At a previous workplace, a very snotty notice came round one day
saying that workers would only be reimbursed for out-of-pocket
expenses; apparently people had been travelling into work on a Z1-n
monthly/annual, then going to a client meeting across town and
claiming for 2xZ1 singles!

Hee ! Since such companies usually provide season ticket loans both the
boss who signed the expenses claim and the accounts dept should know
what type of season ticket the worker had.

A slightly more subtle idea was to use "Gold card gives a N/W card
discount" but claim for a full rate ticket.
