Best I can come up with is that you will have to target in a 10 % loss for whatever is the true reason they are dropping you. Some you will only find out 6 months down the line. Would immagine S/end glass gets really dirty and they would need cleaning more than other areas on a regular business.
There is no such thing as loyalty but most of my custys have been through the wfp learning experience for more than 10 years now and I think we both trust each other, maybe you aint yet built that "trust thing".
I offered them all an extended cleaning period and now clean most approx 2 monthly, I am in a very rural area and they dont get too dirty, most are happy with that and compared to the 4 weekly compettitors my annual charge bill is less than the competitorsm maybe ask/offer them the choice before too many drop you, its better to keep customers than lose them in the long run. It also gives you a very strong customer base but it does take time to develop. As Stan has said we are struggling to keep up and will offer a price saving to the custy by extending to 10 week approx cleaning in the new year so that if we lose more we can regroup back to 8 weeks or even 6 temorarily.
Hope this helps. I honestly think its a glitch you are going through, you aint going to loose all your jobs so enjoy Christmas and re group in the Spring. Thats how I am thinkinking anyway.
