Your movie company company response is very strange. NO theatre has WiFi, period.
Most of the standee assignments aren't worth what they are paying. A 12-hour team build for $7??!! They did do a flat assembly that took 30 minutes once, but that is the exception, not the rule.
Their trailer checks pay a little less that the old company in that the flat fee portion is for the whole day, not paid once for A.M. showings and once for P.M. showings.
