Ooh, missus!
Way back when, I did my work experience at a company whose name shortens to C-T.
I worked in IT Services, and therefore we shortened everything - to ITS.
I wondered why we never used both abbreviations together....until I had just sent an A1 poster to the printer headlined "C-T ITS Workflow". As this was the early 00s, it went on the wall for all to 'enjoy'.
