I have a couple esophageal conditions that result in a high probability of a food bolus impaction when eating (a food bolus impaction is when food gets stuck in the esophagus). There are a few precautions I take when eating to reduce the risk of food getting stuck in my esophagus, one of them being taking a drink with every swallow. Naturally, this means I consume a fair amount of water during a meal.
While traveling to France and Germany recently, I had a bit of a hard time getting enough water during my meal. I can't just ask for a pitcher of (tap) water like I can in the USA. In Europe, when you order water, you get bottled water1, and specifically requesting tap water is bad etiquette.
But one bottle of water isn't enough.
Is there a way I can request a sufficient supply of (still) water, without breaking etiquette rules?
The only option I've thought of is ordering multiple bottles of water (which, depending on the meal and the bottle size, could easily be 4+), but that's: expensive, potentially wasteful (if I order more than I need), and a little weird. I don't mind revealing my swallowing issues, though preferably if I must, I'd do so with a very concise explanation.
1And hopefully I remembered to ask for still water. Getting a food impaction when chasing food with carbonated water (or any kind of carbonation) is the worst.
Edit: Wow, so tap water seems to be more common than I had thought in France. My initial assumption was based on my previous experience, in which I was eating at a restaurant in Paris (I can't recall it's name, but it was quite popular (but not expensive)). When I asked the waitress for tap water as my drink (and declined wine and other drink options), she was visibly shocked and upset. For the rest of the evening she either ignored me (and my wife), or if she had to interact with us, she had a permanent scowl directed at us. It was quite clear she fully expected us to order a "proper" drink. I assumed I had broken some kind of French etiquette rule due to this experience.
