How "safe" is Interaccount Transfers at Party?

Back from summer vacation from Zoo School, and I wonder:

A friend of mine don't play online at all but wanted a poker chips set and jumped onto the Party promotion at pokersource. He deposited $500 by debit card, played the required hands and now have $630 and a poker chips set. Most likely he will not play at Party anymore after this. For various reasons (nothing fishy though) the only practical cashout option is by check, which will cost some $50 in fees.

Do you think Party will play hardball later on if he does transfer all this money to my account at Party, and then I withdraw them to Neteller and pay him in person?
