The front desk has the audacity to email me and inform me after my check-out that one of the 5 rooms that were reserved in my name had expenses on the minibar when in fact, after their "investigation", there was a mistake on their part. This is totally not accceptable from a 5-star hotel. Furthermore, the email was copied to several internal parties initially, with no regard as to whether it will cause embarrassment to the guest. The hotel should seriously audit their processes and align their housekeeping/revenue functions to best practices of other reputable hotels. I am certain that they will lose me as a customer, not only for the room nights but rental of other function rooms for events in future. It might be a small mistake on the hotel's part but a big negative impression impacted on the guest. If this is how you treat your guests, then please be prepared to get ill word-of-mouth from guests in future. I mean ex-guests!
