Why do Casinos do this.

I went to the RIO last night after work and bought 5 $5 St Pats Chips....

Went back again on the day shift....cage manager told me they did not have the chips, as they were not sent over.....

It took all I had to not say you DUMB A** I bought some on the graveyard shift....I just insisted I saw them on the internet and collectors have been buying....she went back and then disgustingly brought me back 5 chips.

NO TOKE HERE....
