Shared user account ?

Hello,
I’m using WC to build a “in house” digital menu order system for a restaurant.

With this system every customer sitting at a table can place orders through a custom shop page and other customized templates (cart, checkout, …).

I’m setting pre-defined user accounts on my WP installation so that each restaurant table is a already registered user account and restaurant manager can easily understand wich table placed the order.

My question is: if i have more than one customer at the same table, can all customers use the same account at the same time to place orders?
