In between the stands there will be water coolers. Visitors can use the water not only for a drink, but also to clean the glass, or to dilute the drinks in it.
Spirits may taste great, but we have to be careful not to consume to much of them. To keep the balance in our body, we must consume enough water.
The water can also be used to clean your glass.
While using the coolers, mind the propriety of the building please.
