Reading these posts, it seems clear that there is something wrong with the culture in Easyjet. Some employees seem to have forgotten that the customer pays their wages. Also that one of the best adverts for a company can be a fully-satisfied complainant. Not only will they come back, so will their friends.
Even if their complaint is not fully justified, it is better to keep them happy. After all, if they misunderstood the T&C, that's the company's fault: it's their job to ensure that the customer has understood them.
It's also clear that the continual sniping from Stelios is leading to short-term planning.
