A customer who protested being treated like a beggar after a shop owner offered free ice cream instead of accepting 10- and 100-won coins [What do you think?]

[Financial News] A customer who tried to pay for two marble ice creams with coins reportedly protested to a shop owner who offered to give the ice creams for free instead, saying, "Are you treating me like a beggar?"
According to JTBC's "Scandal Supervisor" on the 24th, Ahn, a man in his 40s who runs a barbecue restaurant, sells marble ice cream for 1,500 won each as a palate cleanser at one side of the restaurant.
The incident happened after two customers finished their meal and paid the bill. They brought two marble ice creams, and one of them emptied a pocketful of coins onto the counter. The coins were 10-, 50-, and 100-won pieces, totaling 3,000 won.
Ahn judged that it would be difficult to process the payment normally because the customers had been drinking and there were too many coins. He said he would not accept the coins and offered to provide the ice cream as a complimentary item.
The customer then raised his voice, reportedly saying, "Am I a beggar? Coins are money too, so why won't you take them?"
Ahn explained that while he might accept a 100-won coin, it was difficult to take so many 10- and 50-won coins. But the customer insisted that he should take the coins, saying, "If you collect them and take them to a bank, they will exchange them for bills, won't they?"
Ahn again said he would give the ice cream as a free service, but the customer pushed back, saying, "Aren't you treating people like beggars? I don't need your service. Take the money." In the end, after a companion nearby stepped in, the customer gathered up the coins and left.
Ahn explained, "Marble ice cream is something we normally sell, but we also give it away for free to children or group customers," adding, "I offered it as a service rather than taking a large number of coins."
Attorney Son Soo-ho, who appeared on the program, said, "It is the owner’s decision whether to accept the payment, but there is also no reason to refuse something a customer says he will give you," adding, "He could have taken it first and handled it in another way."
Professor Park Sang-hee of psychology said, "Since the owner offered it as a service because it was inconvenient for him, the customer could simply have accepted it with thanks."
