It was a brothel after all as the waitresses' jobs were to serve aphrodisiac filled food to customers.
After they eat they would flaunt themselves since they were all naked, The customers would proceed to the second floor where the rooms are for the deed to be done. Many brothels hold this custom, to have a restaurant on the first floor and on the upper floors there are rooms.
They use aphrodisiacs mixed with food as the rooms above don't have noise cancellation meaning the sounds are very audible.
They are willing to do whatever they can to send people upstairs as it's not cheap to have one room as they charge for every ten minutes.
