<human>: Condense the text into a few key points

Well, today I was at work on cash ringing through peoples food, and as this restaurant is located in a hospital it tends to get pretty busy. So I'm waiting for a customers coffee to finish brewing and am waiting for another 2 people to be finish completing their orders. Now the man was talking to a woman who I figured was around 55-60 years old and he looked about 25 or so, so when he came up she was still getting items and I asked if he was paying for his mom's as well. Well he gave me the most serious poker face I have ever seen and said to me "that's my wife". I must have turned as red as a fire engine while I calmly apologized and scanned my surroundings for any fucking excuse to leave the area and settled on getting some cups to restock while my coworker, who heard everything, went to finish the transaction with a huge grin on her face.
<bot>: Asked a customer if he was paying for his mothers food. His mother turned out to be his wife. FML.
