I see that's got to be a real pain. I think any app for direct payments, like Rev, CA, Venmo, etc. should be perfectly fine for small amounts which won't "call" for attention.

As @ek said, the receiver sees minimal info of yours (@RevTag, first name, and second name initial only), and the app sees only the payment. Robosats users are discrete and don't like any note with the payment or anything, which is convenient for privacy, too.
