If you’ve ordered from a quick-commerce app enough times, you’ve already seen that delivery time keeps changing. What shows up as 10 minutes one day becomes 18 the next. Free delivery appears and disappears. Sometimes you’re nudged to increase your cart value, and other times the app simply asks you to come back later. This is not a bug but a feature of quick commerce operations - this is real-time SLA (service level agreement) management playing out in front of you.
