Sure, it doesn't need to hold them forever, but they can manage them in their own pace, instead of instantaneously converting them to $. This is just a sign that bitcoins are still very volatile and don't have wide usage (otherwise the bar wouldn't rush to convert them instantaneously through an intermediary, but instead would find how to use them for their needs as bitcoins, converting them to $ only when needed to pay the salaries and etc.). It's still great that they even offer an option to pay in bitcoins.
"Manage them in their own pace" entails accepting exchange rate risk, at least until their inputs are priced in bitcoin. Their core business is mixing drinks, not currency speculation, so it makes perfect sense that they don't want to hold bitcoin.
From the bar's point of view this is really no different to a Canadian coming in to the bar and buying a drink with their Canadian credit card - in that case, the customer is debited a $CAD amount by their bank (plus a currency conversion fee) and the bar receives $USD in their account.

That's exactly my point. Dollars are viewed (and are) way more stable and less risky at present. For real bitcoin economy to expand though, this needs to change, so more and more bitcoins are used for direct transactions, rather than for such instantaneous conversion.
