Tipping Culture Expands: Americans Weigh In on Appropriate Amounts.

Americans weigh in on how much to tip for food deliveries, with some suggesting 10-15% for smaller orders and up to 20% for larger ones. Grubhub recommends a 20% tip for smooth deliveries, with an extra $3 to $5 for bad weather. Some argue that delivery drivers should be tipped the same as waiters in restaurants, while others complain about the expanding tipping culture in general.
