Sadly, the large number of semi-incompetent dealers leads directly to increased abusiveness from players. Dealers get paid minimum wage and are thrown to the lions. Some crybabies complain because a dealer dealt them a losing hand. First, players need to bring pressure on the casinos to train their employees. Second, dealers need to ask for training, and police their comrades.
Nobody wants to deal at a table left chaotic by the previous dealer.
It's time to bring poker dealers and casino employees into the 21st Century. A union like the Teamsters or the Service Employees International Union needs to be persuaded to organize these unorganized laborers. The higher wage will certainly be passed along to customers in the form of a higher rake, but that will reduce or eliminate the propriety and need to tip. A change is gonna come.
