I agree with you all! I have at one time or another done all that you say!
I used to finish the bag of Minstrels before the film came on, I've also taken in a subway sandwich and a pear and sugar free lemonade (for lunch), that was when I was watching Super Size Me! I felt so virtuous!
And I'm also too stingy to buy cinema food!
Although we did go to Milton Keynes Easy Cinema once and the big buckets of popcorn were only a quid!
Anyway, WELL DONE Maz for hopping back on the wagon! Keep getting back on and you'll get there in the end!
