In 2019, Robert entertains four key clients and their spouses at a nightclub. Business discussions occurred over dinner and prior to the entertainment beginning. Expenses were $200 (limo charge), $120 (cover charge), $700 (drinks and dinner), and $140 (tips to servers). If Robert is self-employed, how much can he deduct for this event?

Note: please provide your answers and explanations in Word or Excel as handwriting is hard to read. I appreciate it.
