I've only actually seen one of these, the media and social media makes these look much more common than they actually are and more often than not if it's labeled that way, it's probably because it's some kind of suspicious activity, chances are you're not just going to walk into a random bar and then be like get out, this is japanese only, I've never had that and I haven't met anybody who has had that situation.
我實際上只見過一次,媒體和社交媒體使這些看起來比實際情況要普遍得多,更多的時候,如果它被貼上這樣的標籤,可能是因為它是某種可疑的活動,你有可能不會隨便走進一家酒吧,然後就說出去,這裡只有日本人,我從來沒有遇到過這種情況,我也沒有見過任何人遇到過這種情況。
