You are worrying far too much, get out and clean them and explain you are changing from trad to wfp, (use the weather as an excuse if need be)
you wont lose any customers..... trust me, have a laugh with them if they say anything, ask them if they likeyour new posh set up....
then explain the benefits of wfp...
stop sitting at home worrying.
tomorrow night you will post on here how you enjoyed it and most of your customers were impressed....
