A head-scratcher, indeed.

If it's a lot of extra stress, for a measly pay rise (say you only get an extra $10 a week), then SC isn't worth it. If the money justifies the work, then go for it.

As for Customer services - you poor thing! See if your company will allow you to hang a Shotgun up behind the counter, and idly play with an empty cartridge if a customer gets annoying. You could even put in a few fake bloodstains for good measure.

Nah, customer services could be fun sometimes. You get to shout at people for a reason.

Good luck with it!
