It was possible that they would move on to somewhere else but she did not think they would and was willing to take the risk.
She had already spent enough time standing there and there were no signs of them returning toward her direction so it did seem like they would be there for quite some time it was not like she just watched them go inside and then went away right away.
She stood around for twenty minutes or more, then spent some time collecting what she needed, so that was already around half an hour she spent just outside of there.
That would be added to the time it took to follow the hooded male to one location, wait around there, follow the four people, and wait again, only to follow two of them to the current location.
It could be said that the time she spent on them alone was already a big amount.
Ash wandered back from the way she came as she tried her best to remember which direction she had taken.
