I don't think anyone should feel guilty at all, We are adults and make grown up choices as do our clients who choose to visit us. You need to pay Bill's or whatever and that's fine too. If I didn't have neighbours I'd be open for buissness but due to the worry of the rules and neighbours I need to limit or adapt the way I work. I'm thinking after dark and will definitely be down with earning potential but enough to survive and pay my bills. I hate looking over my shoulder but that's how it feels lately, Had to give up my work apartment in first lockdown but I feel privileged I could afford one anyway. We have to adapt and either people will follow strict rules or decide as an adult not to, If I get work it will be from adults that have made a choice to visit me and I know I wouldn't work if I felt rubbish. And I know, From my personal experience, many are lonely too and feel maybe that being mid sixties they want to enjoy life and have some fun.
But i really don't think OP or anyone should feel guilty, Just strange times right now and survival is survival.
