Have tried both locations that you are asking about;
TCM - Very unlikely you will get any "extras" been twice and pretty lax with the draping with both girls who were reasonably attractive, can't remember their names, first massage was much better than the last, likely why I never returned.
Interlude - Been here a number of times, great location, minimal draping (only when face up), no teasing, no extras, have seem two girls here May (in her 50's, average massage, not my favorite but good when in a pinch), Sammie (30's also works at Top Care, cute, great to talk with, good massage, might tease from time to time but has said to me that she dose not do extras)
