Or save yourself a load of money and eat somewhere decent rather than at FB where everything is seriously overpriced so 50% off simply makes it normal.
Or do the Meercat thing get travel insurance for £1.50 and get 2 4 1 on all courses for a year
What app is that please
Think the app I have is 50% off mains for all at your table (may be wrong though). Works in restaurants also. Used it many times.
