I pay corn maze workers $$10 -11 an hour plus FICA, plus a home cooked meal at night for those hear for 8-10 hours on a Sat or Sun.
Haunted section is about the same per hour but is after dinner hours.
Don't worry....just raise rates accordingly for tickets in coming years. After all; your customers will all be getting bigger pay checks so they can afford it. Well, except for those who had hours cut for Obamacare. Oh yeah and those who will be phased out of a job when more places put in order kiosks.
And when the per hour rate gets up to $15 an hour just replace your employees with some $2000 animatronics. The animatronics are depreciable and work out better tax wise than real life bone bags , show up to work on time, never show up drunk, are not hauled away by cops in middle of night for not paying child support, do not need smoke breaks or pee breaks, never ask "Hey can I have the weekend off Oct. 23 & 24th ?"
