Yes but my point is they wait for it to rise. To rise and chose to attack the waiting girl. Not to slither away from, not make small talk with, to rip the throat out of. We see an extended version of the process with Holden. While he's talking to her she makes conversation. When he attacks her (and he makes it absolutely clear that this is what he intends the whole time) she reacts. From the examples we see vampire nature is such that very few of the cemetery types are prepared to forgo a happy meal but those we have seen running or just hanging out in demon bars get a pass from Buffy. Even when visiting the bar is a training exercise designed to show future Slayers how to behave.
