The unicorn was allowed access to the shop. It wasn't somepony's home but a public space. Pretty much like she could enter the bar on the night she lured Mixmaster to her home. A small bell located by the entrance alerted the mares that there was a customer for them and the chime of the bell was something both sweet and pleasant to hear in the air. The unicorn then walked up to the counter of the store as some rumoring could be heard in the background. She let the trio have all the time they needed because she had all the time in the wide world. The unicorn turned herself around to have a better view at the building as a whole.
