With only a single casino,I'd imagine it would be tough.But remember there are 21 shifts in a casino and the same PB only works 5 of them each week.
You can play an hour a day six days a week but if you work the various shifts,it will appear you play much less frequently.
Assume the shifts are 8-4,4-12,12-8. You can play
Monday at 10am,
Tuesday at 5pm
Weds at 3am
Thursday at noon
Friday at 5PM
Sat at 6am
You played every day but the same crew will have only seen you twice.Keep track of the pit,who works when,ect,ect.If you keep a low profile and blend in,you might get away with it for quite awhile.
