If pizza men can /givepizza to somebody even if they haven't ordered it, then the abuse cooldown should be in the /givepizza to the same person .. I mean if it can be abused the person won't be like /call 555 "help me abuse" So yeah what I suggest is a restricted frequency in the /acceptpizza

 I hope you get my point. Good job by the way adding a new job, keep up the good work
