In the past (not during this promotion), I did just that - split the bill for multiple dines. I ate dinner, and the bill was $50 and paid that. Before I left, I ordered 2 meals to take home. That bill was also $50.

I told the server that it was for 2 people and I would like the bill charged as $25 twice. They did it with no problem. The only thing was that I had to send in the receipts to idine to get 4 dines posted (4 @ $25 each).

Besides the extra time and expense for the FAX, I received 4 dines from this restaurant for my $100!
