I actually know this one. You don't bid necessarily by square footage. You are more concerned about volume. Theaters get slammed Friday, Saturday and Sunday and then the weekdays are slower. It's a lot of hard work to get under those seats, even worse if they are recliners.
Midwest market (10.50 per hour) plans minimum of 5 hours a night for 3 people. 4 people on heavy volume days (weekends and holidays).
Ask about annual attendance.... I'd say 12 screen 370k people a year.... 73k plus tax. Margins are lower and the work is harder than you'd think. So beware. Remember... late hours, hard work, 365 a year. You also want to know if it is carpet or tile lobby. Are you cleaning poppers too or anything in kitchen area?
If you want to talk more, message me or give me an email and we can correspond. I'd be glad to talk more with you. This one is actually an area I know I can help on if I see the details of their expectations as it's an industry I have worked with for years.
