I have never been homeless, and wouldn't even begin to equate any of my experiences to such a situation. But the opening paragraphs describing the guests coming in to avail themselves of the services provided at The Boot caused my mind to drift back several decades to when I was a "guest" at a men's dormitory created in a closed CofE building in London (I want to say it was St. Anne's, but it was so long ago, and I don't known enough about London except to recall it was near St. James' Park). Guests were limited to a stay of three nights before having to move on.
Of course, that was not enough time for me to get to know anyone at "St. Anne's" even though, through a series of odd circumstances, I ended up staying there for seven days. I was grateful for being allowed to crash there for the extra time, moving through a constantly changing cloud of guests.
Reflecting on my stay at the time, I realized that if the church of "St. Anne" had not closed down, people like me - and others who were much worse off than I would ever be - had shelter provided to us not unlike manna from heaven. I was vaguely aware that it was more than a building, however, that came to my rescue. Someone in charge had to approve that I could stay more than the maximum three days. There had to be people to clean the toilets, wash out the lavatories, prepare and serve the oatmeal, secure the building 24/7, change the bedding linens, and so on. As a 26-year-old at the time, my consciousness was only marginal regarding such things. I guess one could say I took many such things for granted, except for knowing that The Church was somehow behind a lot of what was made possible.
This story helped create a context for me concerning a situation I was only dimly aware of at the time. And while I am no longer as clueless as I was decades ago, I'm still somewhat naive about, well, just about everything - not just homelessness.
