TL;DR: The receptionist/cashier mistakenly entered our gyukatsu order as a "top up" instead of regular set meals, resulting in an overcharge. Despite our polite attempts to correct the error, she became defensive and rude. Eventually, she fixed the overcharge but displayed unprofessional behavior. Additionally, the restaurant had poor ventilation, leading to oily and slippery floors.

Details: During our visit, we ordered two gyukatsu meals: one single gyukatsu set and one double gyukatsu set. However, the receptionist/cashier entered our order incorrectly in the system. She recorded one single gyukatsu set correctly but inputted the other as a one and a half (1.5) gyukatsu set plus a half (0.5) gyukatsu add-on, which resulted in an overcharge.

Politely, we brought this discrepancy to the receptionist's attention and explained that our single order should not be treated as a "top up" since the "additional order" had the same timestamp as our original order on the receipts. Instead of addressing the issue professionally, she raised her voice and insisted that the order was correct.

We tried to demonstrate the overcharge using the menu, but she rudely refused to look at it, dismissing us with a curt remark of "No menu. Just pay." To resolve the situation, we resorted to searching for the menu online to support our argument. Eventually, she corrected the overcharge in the system but slammed the receipt on the table and sarcastically asked "Are you now satisfied?"

Although the monetary difference was not significant for us, we found this experience to be highly dishonest and unacceptable. No customer should be treated disrespectfully, especially when it is clearly not our mistake. We believe it is important to highlight such behavior as it reflects poorly on the establishment's customer service.

Moreover, we found the restaurant's ventilation to be extremely poor. The lack of proper ventilation caused the environment to become uncomfortable and unhygienic, resulting in oily and slippery floors. While the taste of the food was satisfactory, these additional issues further detracted from our overall dining experience.
