If I was Zenon and wished to keep a good name in the market, I'd politely suggest to the operator that I would not be able to help. The effort required for a two day contract is the same as required for a long term contract. And if an operator has the requirement for two days, I'd suggest that the chance of anybody being paid is quite remote. To be "fresh out of pilots" tomorrow means that they have no way of calling in favours - which has to mean shysters!
