I'll agree on "deserved", "within their area of responsibility", and "[within] their comfort zone".

But I can absolutely decide if something's too much.

It's too much if:
1. The recipient doesn't want it, or
2. The recipient doesn't need it, and it takes a concierge out of service who could be otherwise helping passengers who do need assistance

Escorts in Canada/US almost always fall into category 2, and often 1.

But focusing on 2, if you're the only SE flying that day on a route where J pax are not eligible, and you request an escort from check-in to the lounge and from the lounge onto the plane, and you ask for special blankets to be left on your seat, then I still think it's stupid overkill, but it's not hurting other passengers too much (though at stations where this is possible, the concierges generally perform other tasks too).

But the second you request an escort somewhere like SFO, you're REALLY screwing everyone else. There are rarely 2 concierges on duty. Taking the only concierge out of service when (as an example) on my current AC 738, there at least 30 eligible passengers for concierge services, for a "feel good" benefit, is just selfish.

And I'd prefer if AC told them to just say no.
