I decided to ask my coworker yesterday about the cake incident to see his reaction. I didn't do it in a confrontational way; the conversation went similar to this,
ShellyP: Hey, RK, something curious happened at the wedding.
RK: Yeah? What was that.
ShellyP: Someone took a piece of cake. And it was at W's seat right after you left. Did she take it?
RK: I don't know. I'll have to ask her.
ShellyP: The bride was pretty upset.
RK: What time did they take pictures? (Note: He left at 11 pm.)
ShellyP: 11:30 pm.
RK: 11:30 pm? (He asked incredulously.)
ShellyP: I didn't want to think it was you guys. Cutting that cake was not a good thing to do.
RK: I'll have to ask her. I'll have to ask her if it was her or JW's wife. (Note: JW is our boss!) Sometimes W does things that she shouldn't.
blah, blah, blah, whatever
The rest of the day he spent making sure everyone knew that he was basically drunk before the reception even started and he didn't really anything that went on. Yeah. ok.
