Careful with accusations!
As of last week Christina was still at Island. Don't really know her, but seems like very nice and open person. My instinct says she is not the type or have the need (not crackhead or anything). If not for drug crisis, I have trouble imagining an MA doing that kind of risky thing.
I wasn't there obviously, so I am not calling "Sham" out, but this type of accusation can really hurt a good lady and her livelihood if it is not accurate beyond reasonable doubt. It could be based on an honest suspicion but maybe not deserved. Maybe the wallet wasn't as charged as he thought before he went there. Sometimes I nibble away at my cash from the ATM faster than I realize.
