No, of course not. Depends on the time of day, how your companion looks, and how he/she is dressed. Obviously, they are not going to say anything if you walk in the front door at 3:00 in the afternoon with a guy who looks like the president of Bangkok Bank. But if you waltz in at 2:00 with a twenty-year old kid with spiked hair and wearing a sleeveless t-shirt, you will be pounced upon.
