We were having lunch at a local diner. We were seated at one booth that was in a row with several other booths and trying to converse. However, neither of us could hear the other speak because there were two women seated in the booth directly behind me making enormous noise.
One of them had set up a laptop, a cell phone, an array of papers and an assortment of stationery items while carrying on LOUD conversations on that phone and laptop whose speaker volume settings were turned way up and whose own very loud voice was filling the room with all kinds of business related chatter.
After a while, I got fed up, I stood up, I went over and I spoke up while gesturing toward that laptop:
"Hey! That thing and you are making so much noise, we can't hear ourselves talk!"
You can try to visualize the astonishment on that woman's face. "We're leaving." she said to which I responded "You're leaving? Good bye." and I returned to my booth. Peace was restored to the dining area and I caught a couple of slightly smiling glances from other customers.
That woman was commandeering for herself a facility that the diner proprietor offers to the general public thus denying the peaceful use of that facility by other members of the general public. That level of self-absorption, of self-entitlement or of whatever else that might be called, is beyond justification.
If that woman had given me any backtalk, my further response would have been along the following lines:
"This is a public place, If you have business matters to handle, do it in your office. That's what privacy is all about!"
Of course, it didn't come to that.
