A Reddit user was recently shocked after seeing that the Vietnamese restaurant they dined at automatically billed them for a service charge on their receipt. Key details: Reddit user u/TRTL2k shared a picture of their receipt from Vietnamese restaurant Pho Ha Noi in Cuptertino, California, on the subreddit r/mildlyinfuriating on Sept. 13. How much they paid: The total amount u/TRTL2k paid for their meal was only $49.50, but because of the sales tax, which is listed at 9.125% ($4.52) and the 18% service charge ($8.91), the Reddit user had to cough up a total of $62.93, which was $13.43 more than their meal.
