My wife and I will be in Las Vegas in 25 days . The last time I was there was in '99 and at that time I wasn't a collector. Here's my question. I'd like to get some house chips { especially $25's } in the best condition possible. Will they give them to me at the cage ? We'll also be visiting Henderson, same thing there ??? I've read a few times that some collectors tip the cage worker. I know it's up to the individual but what's considered appropriate ? Any info would be appreciated.

Thanks,
Victor
