I stay in motels/hotels all the time. Only the cheapest of the cheap...the lousiest of the lame, reuse card envelopes. It is so incredibly unhygienic and screams of poor management and does not imply "Conservation" or whatever other reason they might give.
AND no Febreeze for maid staff to use. Again, that is a staple in decent places as it absorbs the odors and does not mask them like their green stuff does.
Just poor decisions by management. Way too cheap.
