Not funny
Union Jack liquor store, located in Louisville, CO had on their marquee “Thanks China”, and advertised a beer special for $14.88 (White supremacist number). When called out by the community, there were multiple stories given by the owner. As quoted in the local paper, he expressed that he has a sister in law who is Chinese, and who thought it was funny. Likewise, he defended the use of 1488 by saying that he didn’t know that this was derogatory, and “still doesn’t know what it means”. The latter assertion seems very unlikely.
