Usually sexual harassment laws apply to the employer providing a safe environment rather than the customer.
yes, that's what I meant: that the employer probably has protocols/rules in place about this to make sure they are providing a "safe environment". Anyway, I'm just guessing. Maybe airlines don't care if the flight attendants work in an environment where the customers are watching XXX on laptops as they service them. Uh, you know what I mean. LOL
