There are lots of interesting comments here regarding perspective on how a church manages their needs.
Let's look at it from the other side. While some comments here speak of power by those on committees or groups. That has caused frustration on the part of an LCO trying to provide lawn services. Remember, there are those given the responsibility and authority to make decisions regarding the work on behalf of the church. These folks could be volunteers that are given the task on a rotating basis, they could be part of a staff hired by the church. In any case, they are given the task of getting the job done, either by hiring it out, or by managing a no-pay volunteer(s). Some here may call it power, and in some cases their actions may be an overzealous attitude. However, in most cases, they are merely doing the job they have been assigned. And, they are charged with being good stewards of the resources afforded them.
I've been part of these matters on both sides. While some here are frustrated, perhaps you have not been part of a leadership team in which some choose NOT to exercise their power and authority to get tasks done. Yes, that is very frustrating on the other side. Also, I have donated my time and services to get the lawn services done. And, no, just because an individual donates these services does not mean they are immune from criticism on the quality of work.
Many threads have been posted over the years on the customer base we have, whether it be residential owners, landlords, businesses, national chains, HOA managers, etc. The range of customers is very wide. Somewhere in that mix are churches. Thinking that a church should fit the mold of other customers is to not understand the nature of the client. Further, churches can be very different, from small ones with a single contact given full responsibility for decisions, to boards (e.g. Building & Grounds, Facilities), to Business Manager, to Facility Manager. One recent thread discussed the Pastor wanting to make the decision on a string trimmer purchase for the church (this one has much greater problems than lack of a string trimmer, ... another story). Unless the LCO understands the dynamic of this kind of client, then perhaps they should pass on the opportunities.
