This is sweet.

You can now see how long each line is for bathrooms, concessions and beer lines at Buffalo Sabres games inside Key Bank Center.

On the OneBuffalo app for your phone you can see how long each line is. We're all wondering, though, how does it work?

There are sensors above the lines that will transmit and let everyone know on their phones AND on a sign how long waits are.

It won't just be on your phone. Vertical monitors, four on the 100 level, and three on the 300 level, are also throughout the concourse and will display the wait times", according to WGRZ.

The Bills only have this for the gates to get into New Era Field. Maybe they should get them for the bathroom and the girls can find the shorter lines so they don't have to use the guys bathroom all the time. lol
