When I fixed PCs for a living, we were issued with wrist straps. I used to wonder if it was more about how professional we appeared, given that it was field service in homes and offices. Myself I’d previously either left the base unit plugged in with the mins switch off if needed, so that the case was grounded. You can’t really work inside without touching the case, so you are then grounded too. Back when I was a student we used to use the stainless drainer in the kitchen for our electronics projects. I used to find the strap a pain as it would always catch on things, plus if it isn’t at the tip of your finger I wonder how good it is at getting rid of all the charge. As others have said, it really can’t hurt (unless you catch it on the case) to wear one.
