Convenience Stores & Cafes' 'Small Acts of Kindness': Is Paying for Strangers a Warm Tradition or a Store's Hassle?

Have you ever seen the heartwarming phenomenon of 'suspended coffees' or 'buy a drink for the next person' at convenience stores or cafes? Recently, many netizens have shared their personal experiences on community forums across various regions: a customer in line might smile and tell the cashier, 'Please give the second drink to the next customer!' simply because they were taking advantage of a buy-one-get-one deal; or a stranger behind them might kindly cover the difference for a student who didn't have enough change. These small, unexpected acts of kindness often brighten the recipient's entire day. This practice of 'passing on cuteness and kindness' has resonated widely, with many netizens praising it as a display of Taiwan's unique human touch, even inspiring more people to join in and form a chain of goodwill. However, some raise practical concerns, questioning if such actions can sometimes cause difficulties for cashiers with POS system transactions or quantity checks, or even be exploited by those with ill intentions, thus twisting the original good deed. Do you believe these sudden, unexpected 'small acts of kindness' in daily life are truly a glimmer of warmth for society, or are they acts of self-gratification that inadvertently cause trouble for the service industry and existing rules?
