Guilty as charged m'lud! But, for the most part, the jobs I had didn't entail the need to claim expenses. And so, the full extent of my 'pilfering' - as opposed to actual 'fiddling' - amounted merely to the acquisition of the odd item of office stationery, such as an alphabetically-indexed notebook [which is still in my possession some 40 years later] probably a few ballpoint and highlighter pens and, perhaps, a couple of rolls of Sellotape, &c.
In fact, on the one occasion that entitled me to fill-in any form of 'chitty', my then boss [a miserly old] instructed me to use public transport and *retain my bus tickets for inspection. As the task I'd been assigned to involved knocking on doors and/or the random distribution of sales leaflets in various streets within my home town, I decided to be "resourceful"
by using my bike and, mission accomplished, rode round to the main bus terminal ...
where I gathered up as many discarded bus tickets as I felt would be required, and duly presented them in return for an appropriate reimbursement. *"Problem" solved!
