The WORST is when people lean on their vendors for this crap. You know, cruise into the audit room and ask if anyone wants to support their kids random cause. WTF are the auditors suppose to say? Doesn't matter what you are doing, when client's ask for that crap it's a huge pain the ass.
Even worse than this, are employers who won't let you get reimbursed for being strong armed by your clients into supporting this crap.
