I tip the ticket writers cause you never know when your going to need to ask for something,or have them do for you.I have asked them for several things when i'm in Vegas.When gaming today is hard to get,and i would have missed the day they come out,i have had the gaming today given to the sportsbook people in a manila envelope to save for me and it is always honored....Also i ask them a lot of the time if they would give me a print out of all the lines i may want and what sports i want and i have no issues.There are a few more things they have done for me,so i have no problem tipping them,...i remember there was a thread here asking if people tip a to go order,or a pizza pickup order and i think a lot of people said yes,well all they are doing is handing you a box of pizza and taking your money to pay for it,..now i have no idea why anyone would tip for that,..anyway i'm done babbling here so i'll stop here
