回複：I use computer at a library.

Library has security camera too. And you fingerprints are on the keyboard. When you check out, you are photoed. Oh by the way, the store had already installed camera, just in case when you want to return the chair. Other stores around may also have cameras which catch you carrying the chair away.

All said, if they really really want to get you, you are caught long time ago.
Never take these issues to public
The more you post here, the easier others figure out who and where you are.
The more interest you draw, the bigger a target you are.
The more you try to make up, the better the chance more things will go wrong and someone can get you.

So pray and do not do it again. Baiscally, you suck. but you still deserve a life and just move on.
