they could of hired like a private investigator or w/e they are called...thast the only explanation i have for them getting calls everytime u get bud, but if thats the case then when u get bud dont be like obvious about it, dont go into ne ones care for a minute then come back out right afterwards, maybe just emet some kids somewhere and chill with them for a while and casualy make the deal so that its not obvious, i dunno...good luck
