$7 for a job and $80 worth of tickets? What kind of blind check was this? I have done all kinds of theatre shops for CFA and I do not recall a blind checking for $7. Is this the one that required you to purchase tickets for two, count patrons for each showing and purchase more tickets for another showing? You are supposed to be paid for each screen showing. And reporting online should be easy since you would just have to record what you have noted on. Plenty of time to meet the deadline. The hard part was gathering all the info and mailing them. If you did not have to mail them, then I have never done that shop. Especially if the fee was $7. Blind checking are usually paid more than overt, even if your tickets are reimbursed because it's hard to actually do the counting without the cooperation of the movie theatre management.
I don't think that giving you their competitors would help because I think CFA theatre checks are easier to comply with. And this one, since you were supposed to be paid for the ticket, you could even watch the movie.
