We seem to agree about La Poste, but I have never experienced a carrier texting to say the package had been left at a point relais. In fact more and more call and say that they will be there soon just a few stops before they get to you, and several have in place a system by which you can follow the progress of the delivery van on an inter-active map.
Nor do I agree about the old chestnut about customer service in France. It may not be top in large national chain shops, but if you deal with local individuals it is often superb.
My Pharmacy, local food businesses, the cafés and restaurants I visit offer personal and thoughtful service, and the Nurses and Physiotherapist who call several times a week are wonderful.
