Being extra polite, friendly and nice can backfire and make the grumpy flight attendant even more grumpy. Sometimes with honey you can get stung by a bee. Just act normally and try to minimize contact and chatting with the flight attendant. It also makes no sense to complain in-flight since the crew has all the power. If it really gets that bad, wait until after the flight to make your concern known on a survey or an online customer service form.
