If it this was one of the laundromats in Earth, they’d also iron the clothes after washing, but the laundry agency that Ryouma built was made specifically only for cleaning.
All the cleaning were left up to the cleaner slimes. And the cleaner slimes would either go inside the bag or put everything including the bag inside their body, then wash it. Because of this, they were also able to prevent losing laundry. After all, without even taking out a single piece of clothing and finishing the laundry in just one room, it’s only natural that nothing would go missing.
As for providing services other than cleaning, at most there’s only folding the clothes in this world. If that kind of service is desired, then Ryouma could just have someone do it, or do it himself. Or alternatively, hire the people who do their laundries themselves and wouldn’t use Ryouma’s store
“Looks like it’s going fine. Do you have any questions?” [Ryouma]
“Has this really become clean?” [Karma]
“We’re not really seeing the kind of results we’d heard from Serge-sama.” [Karla]
Because the twins said that, Ryouma had them open the laundry they got from Jeff and had them use ‘Identify’ on it. Having understood that the clothes were clean, they felt admiration for the cleaner slime’s ability. They had heard that the clothes from Jeff were covered in monster blood, so they were quite surprised when they found out there wasn’t even a trace of it on the laundry.
After that, Ryouma distributed the bags targeted to individuals to the 11 for free as a service. And because Wogan announced that he will be taking the group laundry option with the staff, Ryouma passed them a giant bag that could take 35 people’s worth of laundry along with 35 individual bags for free.
