If they applied for 7 slots, but hand back 4 you may be right in that they wanted to pick some days out of those, thats your glass half full.
However it may also be the case they have decided they cannot fill 7. Wouldn't they apply for say 3 days and then increase if demand was there ,not the other way around.Thats the glass half empty I suppose
Anyway hope they do come as I pointed out.
