But in relation to the scenario you mentioned of picking up an item on the way home while your partner was at Whole Foods, yes, a simple SMS saying "I'm picking up cheese, is that cool?" just works. If what you meant by that scenario is that there are many people who co-habitate and frequently and simultaneously do grocery shopping at different stores, then I can't really comment on that.
