Good to know you advocate slyly swearing at your customers in a foreign launguage.
Not at all, really. Once, however, I wish I could have intercepted the thoughts of two flight attendants resolving a quarrel started by some stag-party members aboard the plane. They acted very professionally and didn't say anything, but their thoughts might have been very close to the above. I criticize FR myself on some occasions, but please find better reasons to mock the crews.
