Is ordering at Rou friendly to first-timers?

Rou is a ramen shop with a distinctive menu and way of ordering. The owner is the ramen Armor-san.

You want to eat. You have the money. But you don't know how to order. At shops, that's the kind of thing that can stop you in your tracks. What ordering at Rou makes me wonder is how a first-time customer gets used to the shop.

Having a unique way of ordering doesn't by itself make a shop unfriendly. If you can tell them your preferences with set phrases, that's probably handy for regulars. So how does someone who doesn't know yet find out?

At a real shop, a sample order would help. You could also have a friend next to you explain. But could you order on a day you came alone? A shop you can use with someone and a shop you can use alone without getting lost differ in how easy they are to walk into.

What helps at a new shop is being able to see how to order, and being able to ask again if you get it wrong. Even without a friend, those two things seem like they'd make it easier to walk in. Making prices the same alone doesn't close gaps like these.

In ordering scenes, I want to check not only whether someone said it right, but also who helped when they got stuck.
