i dont think that you can but you can open yourself up to a lot of unnecessary and embarassing attention. Where im at someone actually did that and they got the cops called on them because one of the pharmacists thought they were going come back after the store closed steal the tylenol and sudafed and make meth my advise before you do dont.
I don't think that you would get arrested (probably depends on the country? anyone?)
However it would be strange, unless you have a really valid reason for doing
it. Someone might think that you are aiming to steal something or just that you
are plain crazy.
Its for my job
