Well, maybe different people who live in different countries on different continents have different ideas of what a bar is. Where I live you don't go to a bar to drink although you usually drink something when you're in a bar.

But then ... maybe you work at a bar? You didn't describe your office.

Because you're being a douchebag who is taking up way more space by having your laptop out and requiring a clearance to help prevent people from stepping into the danger zone where they might accidentally spill their drinks onto said laptop.
