Not sure what to do about job at driving range?

sure is but thats just what you gotta do somtimes. I work at a golf corse and people try to abuse the hours best thing to do is mabey put the closed sign up once you are done selling baskets of ball so mabey they will get the hint or somthing like that. Its possible that they might not relize that its 9:00 as well cause time flys when your golfing so mabey if you tell them when they come in like 40 mins till the range closes they migfht be more conciderate.
