Personally I think it's ridiculous that sparkling water is somehow stocked in the bar carts and not with the soft drinks, but that's a minor catering issue. Yes I said minor because IMHO it is. This only happens ex- some ports, and (as usual) it is not consistently applied from many departures on QF from LAX. (Also note it's not only QF that do apply this.. well not rule, but policy - I've had it on UA previously and a euro carrier like LH years back).
I stil say that if a "reasonable" explanation/reason (of course one's definition of what is reasonable will vary widely) of why they can't provide sparkling water, or a bloody mary, or whatever. and a promise and follow through to provide ASAP after TO should be accepted.
I would consider it far less reasonable or good customer service to just say "No" with no explanation or empathy.
We weren't there. We don't know exactly what the interaction was. That's not me defending QF.. I'm just trying to say there are ways of handling this kind of thing, and there are also ways of reacting to it.
I find in my professional life where I have to give a degree of customer service when things go bad (in IT) that most poeple are far more reasonable andunderstanding when given an explanation. Even if they may not understand it, being given a reason and a measure of understanding is usually better received than just "No".. but that's just me.
I remember one time on EK leaving some place they only offered Moet as a PDB in F rather than the Dom. I enquired about it and they expressed it was a similar situation to this. I just said OK no worries I'll wait till take off. It seemed a bit silly and penny pinching for a carrier like EK, but that was what they were doing. I'm not going to jump up and down and call it disgusting or a PR disaster.
I think most of us are reacting to the extreme language being used to describe an annoying and disappointing situation but hardly a "disaster" of any sort. Remember any landing you walk away from is a good one
