I think it depends on the sales associate and location as well. I was always offered champagne or drinks with their chocolates in most locations I went to (Melbourne, Tokyo, Singapore, US) prior to Covid. During early Covid I didn’t physically visit any boutiques for about a year so I can’t say if they continued to serve them, but since around December of last year they resumed offering drinks and chocolates again.
I’m so sorry you haven’t had a great experience with the service! Any chance you would be able to switch SAs or location perhaps?
To bring it back to topic on the price increase, none of my SAs in the US informed me of the price increase but my Singapore SA kindly did and asked if there were any items I wanted to put down a deposit for to secure the current pricing. I appreciated this and ended up placing an order even though I wouldn’t have if she didn’t ask. I believe this is much better customer service to proactively reach out to clients to get more sales but perhaps not every salesperson is this forward thinking and rather wait for the sales to arrive on their lap.
