Restaurant, Bus, Train

So, I just wanted to briefly talk about how the 3 of those things work there. All 3 seem to work on a philosophy of saving you time.

Restaurant: generally in a family type restaurant such as Udon place or family restaurant, there is a button on the table to call a waiter. This eliminates the issue in the states of waiting forever for a waiter to come take your orders. It also eliminates the issue of the waiter coming to your table bothering you with the phrase "Is everything ok?"

Bus: Generally the way the bus works is that, the bus has 2 doors, the middle and front door. You enter through the middle door and take a ticket form a machine. The ticket has a number, there is a board at the front of the bus which gives the price from the bus stop you got on (number on the ticket) until the next bus stop. When you get to your stop you go up to the front and drop the ticket along with the payment into a machine next to the driver. Obviously sometimes you can pre-pay a ticket from point A to point B, in which case you just drop the ticket.

Train: Generally on local trains and metros there is a board at the station which gives the cost of a ticket to a certain station. You buy a ticket that is worth a certain "value", or the cost to your destination. If the train you're taking is an express has reserved seating then you'd have to bay for a specific time and date. When you get on the train you pass through a gate, using your ticket to open it. When you get to your station, your use your ticket to get out through another gate. On a local train if you pass your stop, you would have to go to the fare adjustment window and pay the extra cost. I'm not sure, and don't really want to know what happens if you lose your ticket. In more rural areas on small stops there are no gates, so the tickets are sold and collected by a cashier. When the cashier closes, one of the conductors from the train might collect some of the tickets.
