The latest gaffe creates a new headache for HBO, which handled the coffee cup incident deftly, with a lighthearted statement.

“The latte that appeared in the episode was a mistake. Daenerys had ordered an herbal tea,” the company said.

The final season of the worldwide phenomenon has received underwhelming reviews and a frosty reception from many longtime fans, who complain the show has been rushed.

For some, this latest modern intrusion only made things worse.

More than a million people have signed a petition urging showrunners to “remake ‘Game of Thrones’ Season 8 with competent writers.”
