Yes they do. I always walk right pass them in line with my ticket in hand. Many times i will hand one or two to some one in line.
Personally don’t know why they wouldn’t come with out a ticket to save a little money. You can walk up and buy a ticket before a game at the cajun dome or cajun field starting at 10 AM in the morning. Unless you wait until 20 minutes before the game there is never a line. So if you get there an hour or so before kickoff get your ticket first you won’t stand in line and you never have to worry about a sell out.
