What is the best way to handle this situation? (see details)
I have to go in the warehouse with the paperwork for the load I'm delivering. 6 dockworkers all said some extremely vulgar things (explicit yucky things). They said all this in their native tongue (not English) obviously unaware that I could understand them. I didn't respond, just put the paperwork down & retreated to my truck. I have to go back in when I'm unloaded. Would you suggest that I continue to "play dumb" or maybe just tell them to have a nice day...in their language?
