COSTS and STANDARDS

Can anyone please tell me why oh why are so many nursing homes and nurseries with the larger companies for disposal of there waste. Been to an appointment today and they are paying £11.00 per bag and disposing of 60 bags per week. Who in there right mind would do this,and to make it worse they are in a 3 yr contract well the last 12 months of it.
When will the healthcare industry wake up ,we independents will save you at least 50% on those costs and more.I also took a video last week of a very well known hygiene company(prob biggest in uk) where one of there operatives firstly walks through a super market with dirty sanitary units ,then to behold follows me upstairs to the public restaurant and does exactly the same again ,walks past tables with food on,high chairs,where are there standards,infact where are there modesty bags to hide these units.
