<raises hand> Yep, I do this in most of my apps, especially where I have to pull data from a legacy system that give me NO feedback progress. Rather than handballing this 'quiet time' to my users, I tend to create timed progress bars that try and 'guesstimate' the timeframe based on historical transactions of the same size.

Or else I will randomly display various loading messages that are quirky but not relevant. Must admit I was highly inspired by the old SimCity loading messages, which seems to have further inspired the devs at Slack etc. with their creative loading messages.
