"Tip creep" has hit the race and sports books, also. I tend to agree with Rob Singer on this, and I am just not going to tip, no matter the payout. Thirty years ago, sports ticket writers were rarely tipped. Now the tourist-weekend-warriors in Las Vegas tend to tip ticket writers fairly frequently. There is no way I am turning an 11-10 scenario into something more like 6-5. And on the occasions one is able to negotiate -105, it makes no sense to tip and partially negate the work you did to get the -105.

To put this in the overall service context, I do not need a human ticket writer. He or she is extraneous to the wagering, which can often be done at a kiosk or with an app.
