Can I say here that they aren’t your friends, they’re your work friends. If you changed jobs would you ever see them again? It’s all context based. At the end of the day you’re all there to do a job. Their actions are making it uncomfortable for you to do yours. They should be professional. If they are going to blur the lines by being inappropriate you have the right to set that boundary.

To the bar tender, deliver your lime in seriousness. Don’t be soft or coy. Make a face and say “that was inappropriate, do t say that to me”.

Your current comments are being misinterpreted as playfulness. Leave no room for doubt that you don’t like it and want it to stop. “Wow, that was rude.” Or “yuck, don’t say that ever again.”
