The person who remembers your order may be noticing more of your routine than you realize.

Being recognised in a shop or a cafe is a small pleasure and a piece of information. Someone has been paying attention across weeks, and it extends past the order to the days you come in and whether you looked well. That is one of the quiet ways strangers keep an eye on each other in a neighbourhood. It works in both directions, mostly unnoticed.

Learn one name where you are already known, and use it. Notice what you have absorbed about the people you see regularly. If someone you usually see has been missing a while, it is not strange to ask after them.
