I've never had to before with AboutFace, though I will admit I haven't done much work for them.
Unfortunately, I do usually need to chase Strategic Eval. I would say that I wouldn't work for them again, especially since they are normally reimbursement only for the shops in my city. My issue with just not working for them is that they are gas shops. When you need gas and don't have another gas shop, getting it reimbursed at least is a plus. Thankfully I had 10 shops of my favourite gas shops this month, so I'm good on gas.
