Sushi: conveyor belts and counters

Getting a seat. Large conveyor belt chains often use a reception machine or app. Take a ticket and wait for your number.
Ordering. You can take plates from the belt at many shops, and most also take orders on a touch screen. Many screens can switch to English.
Price. Plate color or the screen shows the price. Do not put a plate back on the belt once you have taken it.
Tea. Many shops have green tea powder at your seat and a hot water tap at the counter.
Paying. Staff or a machine counts your plates. You usually pay at the register, not at your seat.
