Avoiding too much conversation with food delivery riders is not a positive or appropriate attitude. Most food delivery riders are very hard-working, and they are just working hard to earn an income to support their lives. If you really don't want to have too much communication, you can simply say "Thank you, just leave it here" when the rider arrives, and use relatively concise and clear language to inform the other party of your needs. This not only expresses basic courtesy, but also does not lead to too long conversations. We should respect every worker, understand their work, and give them due kindness and consideration, rather than deliberately avoiding communication. They provide convenience for our lives, and a smile or a warm word may make them feel a little comfort in their busy work.
