The 25 year rule is long-standing (over 4 years) and yes, whilst it may seem excessive to some, it does work for both our regular customers and ourselves, so I make no apology for it. Also, within the last couple of weeks, there has been a clamp down by the Taipei City Government on the maximum capacity we are allowed to have within the premises and applying this in-house rule more stringently at my own insistence is one of the ways that our regular patrons are able to use the facilities. We have a membership system and having a membership card as a recognition of regular patronage is helpful in getting in, even though at times when capacity is reached it may be that they too have to wait a short while before getting in but they receive priority. The rule is not based on or targetted at any ethnicity either.
The above notwithstanding, I understand the contradictory remark of the person on the door and apologise to both yourself and your wife for any actual or implied insult.
If you wish, you can PM me and I can arrange a membership card for you both. We do have people below 25 who are members.
