In 2019 my business partners and I took a client for lunch here in Oshakati at the local guesthouse. The guesthouse is our resident water hole and the waiters know that when we ask for mineral water, he should bring us each a pint of lager.
Unbeknownst to us the client, who was staying over at the guest house, took the liberty of ordering 4 mineral waters (intending to drink water). He was quite shocked when the waiter brought beer. Luckily he was a raw Irishman and needless to say, we had a few mineral waters that afternoon.
