Just getting back to the "Best" fares.
How are they intending to give out the refreshments that come with them? Passengers will be seated all over the plane, so the cabin crew will need some form of seating chart and then they'll need to know that people haven't swapped seats to keep families together etc.
...or just a couple of words or a voucher printed on the boarding pass, so the passenger shows his/her boarding pass and gets a free tea or coffee. Don't flyBE do something like this for their Economy Plus product?
