I know it sounds daft, but yes, that is exactly what they were expecting, that's what I was told.
I take your word for it. Any start up business is very lucky to have immediate and sustained success so I cannot decide if it's stupidity or arrogance for them to think they would sell out. If they did their sums on full houses at £38 plus drinks then I imagine they're f***ed as they have another 4 years to go.
