Excuse me , sir . Can I help you ?   I'd be glad to have your help . Could you make the air-conditioner cooler ?   I'm sorry . We can not regulate the air-conditioner . As soon as the plane takes off we'll be able to get better ventilation , and the temperature here will drop . Let me get a wet towel for you at the moment .   Good idea .   Your wet towel , sir .   Thank you . Could I have something cold to drink ?   Yes . We have mineral water , orange juice , coke , which do you prefer ?   Orange juice , please .   Would you like some ice in your drink ?   Yes .   How much would you like ?   One or two cubes will be OK .
