“Tax law, like Congress, works to distance itself from common sense.”
I don’t always eat lunch, but when I do it ‘s tastier when subsidized by the government. Yum! Here is an overview of the rules.
50% of the reasonable cost of business lunches is deductible. (Transporters can deduct 80%*.) If it is appropriate to bill a customer for lunch, you can deduct 100% of the cost and the customer is stuck with the 50% limit. I haven’t done this yet, but you may have a construction contract with travel and meal per diems or some such. [···]
