I installed the game a couple of says before and i've had issues with interacting with customers, orders and tables :( I think it's a problem related to the gam
I had the same problem, if you find it hard to interact with the tables and such, press the up button (the button on your keyboard with an arrow pointing up) and then click the space bar and it should let you. If this doesnt work you're probably pressing in the wrong area and not lined up properly with the thing you want to interact with. Hope this helps! (also ik this post was months ago but also for newer players
