Planning or making an appointment never served me well back when a couple busy spots were still in business, then I started to text with a couple favorites so as to walk in when they were next up. There were certain times during the day that a line of mongers were literally waiting in the lobby, I’m sure it pissed some off when I would walk in as they’re waiting and mamasan would immediately let me in. Then I changed things up with visits late late night, a few late visitors would walk in, but not like at peak times. In my experience or when I first began visiting FS shops, calling ahead and making an appointment, I recall having to wait regardless, seems the girls would serve someone even though I called ahead, i completely understand since it’s a cash business and a customer walks in cash in hand, so to speak, I scrapped that idea after a couple tries, I’ve also heard guys complaining to mamasan because they had an appointment, the provider is busy and he has to wait or take another girl, crying like a baby as a matter of fact.
