I'm trying to create a POS for a friend.
The store is provide services, so no inventory is needed.
The menu service consists about 60 services, and about 10 technicians.
The menu service is look similar like this: https://www.youtube.com/watch?v=GzkAhSxupGA
I want the technician select his/her username before select the service buttons.
Then those services and the username is popular in the register menu.
Each button is designated with service name and a price.
