Casinos also thinks of altering their lucks. It would bother all if after the change of dealer, everyone lost except the dealer.
Since players also are also leaves the table, I guess theres lot of you who are also annoyed by the change of dealer. Does it occur to you that casinos also wanted to change their luck thats why they replace dealers every time?
No, the reason for this is actually very simple. The casino knows that there are dealers that might be corrupted. So to make sure that there are no collaboration between a specific dealer and a customer, they change dealers on a regular basis.
So, if a customer change tables to stay with a specific dealer, "red" flags are raised and they look deeper into that. It is irritating when they do it too often, but some providers are over protective.
