Entity Table automation

hello

i have a two problems i am facing first one is that i want when i open a certain table automatically a customer account should be assigned to the table or ticket, and then i have taxes and services i want to remove from these tables automatically

in need for support and help for the following

Tax wont be that freely removed, youll need to change something which is tax relivent like maybe department or soemthing.
Serives and discounts can be manipulated with automation so they can be changed on entity change etc.
Why so you want a table to use a customer account? Why not use a customer and in turn just use the customer account that comes with it
