"Many Japanese izakayas and ramen shops cultivate a warm, rowdy vibe by encouraging staff members to shout “Irasshaimase!” when diners enter. However, the chant is for employees to welcome guests. While dining at Katsuya (a real Japanese restaurant in Brentwood), Larry decides he’d like to use the phrase as well, screaming it at his date and annoying the cooks by stepping on their line. Later in the episode, he hollers it to his friend at the golf club, and then at a stranger, who doesn’t seem to know Larry enough to even respond. When American diners visit restaurants in other countries, it may be perceived as respectful when they use simple phrases like “please” and “thank you” in the local language. But imitating an accent, or the volume of a declaration (which, even in a loud izakaya, is notable), is insulting mimicry and racist even by 1980s standards, nevermind in 2021 when the episode aired." - Corey Mintz
