A wise man tips the bartender when he sits down at the bar....
That's worked before HD cameras over every bar and
pour meters on the bottles No where I go or have been have I seen that.
Then you don't go out nearly as much as we do and since you routinely live out of country I know you don't visit the same clubs we do
The pour meter is ultra common. Bar owners install them then the camera guy can count how many times your bartender turns over the bottle.
Bar owners do this to prevent bartenders from stealing alcohol for better tips
