When it comes to leaving a tip, most customer stick to 'social norms' and give their server anywhere between 10 to 25 per cent. But knowing who to tip and who not to tip has become a debate in many American states, as the country's tipping culture continues to evolve.
One 24-year-old man knows this all too well after working as a DoorDash delivery driver. He explained how he was visiting his boyfriend's family when they decided to order a $150 (£121) takeaway from DoorDash. Out of interest, he asked his future sister-in-law how much she was planning on giving the driver as a tip.
