Genuine question: I have never been store front. What is the advantage of store front vs AAMP? Won't it feel weird to wait in the waiting room with some other dudes?
Ya, that's not a thing at an AMP. If no girl is available, they either kick you out, tell you to come back, or situate you in an empty room.
As for AMP advantages:
1) WYSIWYG, none of the catfishing photo guessing game BS. The coutner argument is that most AMP's are milfs and gilfs. Well, the well reviewed ones all have 30's which is the average age of K-AAMPs. (If you think a K-girl is in her 20's, you're probably white, and 9 out of 10 times no she's not) Sometimes there's a 20's girl especially the viet stores.
2) No screening.
3) The convenience of walk-in as soon as you're feeling it, instead of booking it several hours in advance.
4) The option of just a handy or QV if that's all you wanted, or a massage with an HE (which is a legit preference to some) K-AAMPs are fixed at 1 hr. SH technically has HH options but SH is only half K-Org and half C-org, run by a Chinese operator.
