At my local casino they basically pay attention and record the amount that I buy in at and presumably have that associated with my player's card. For example, I may buy $200 in chips, then move around tables and eventually cash out later (not even the same pit where I cash out). Would it be advantageous of me to buy $1000 in chips, for example, and just stash the majority of it in my pocket and don't even use it until I cash out at the end?
I figured if this is an easy way to accumulate more comps credit, then I might as well.
