2=3
always the big one in the morning. then hopefully a medium. then a small single room fitted on the end.
Wouldn't this be wonderful in an ideal world......perfect for doing and for scheduling 
you don't need an ideal world you just need to book them that way,
unless they can do no other time i won't let a customer book a single room for 8am.
i tend to book all big jobs for a morning I just just say to the customer
" the next space we can book this job is 8am next Wednesday" if i single room needs cleaning i say
"we have the last appointment of the day next week on tues & friday"i just offer appointment times that fit into this scheduling procedure
