It can definitely come in handy speaking on the phone in all sorts of situations.
At a job once, I was on the phone with a customer and was spelling something or giving a string of letters (can’t remember what exactly), and I was having trouble thinking of good words to use. “D as in… duck” not realizing that could’ve sounded like B as in buck or T as in tuck. “F as in…” (don’t say fuck don’t say-) “fu… fun.” “V as in… Vin Diesel.”
Customer was laughing, so I think it went well.
Interesting, I have had a nearly opposite experience in the past.
At one retail job I had, if you needed a shift off, you had to find someone else to agree to cover your shift. That was basically the whole process of getting out of a scheduled shift. Take a shift off, fine, but it was the responsibility of the worker who needed a shift covered to get that shift covered.
