Right Brian, same thing happened at Elko where they had two tables, one with "roulette" chips and one with H&C. (Only one table open except a few peak hours on Sat.) Next trip one table, all H&C (which I had already harvested one of each)
Next change, all were gone, new chips and two tables again. Enough to drive someone crazy! lol

I drop two or three chips in my pocket at most. I don't want to harm the casino in any manner.

Mel has it right. (as usual) Get ugly chips and none of us will want them. The other object is get chips that cost less than the Min. buy in price, and make a profit on all the collectors who want complete sets.

To answer your question about, what's a complete set? I would say the standard set of seven that usually appear at one time, and not, every chip that has ever graced the tables.

Think about this... over 150 Millenium chips issued, I have two. Thousandss of roulettes issued, and I can never have enough? lol
