I've received abuse, whines and moans for not offering bookings during lockdown and restricting them (including having received advance bookings) as I start again.
And some have gotten stroppy because they've gotten a negative Covid-19 test result, so they must be safe. Also had a resurgence of wanting to know when my 'fully booked' booking finishes, so I can fit them in.
When I explain that's it until my self-imposed gap is up, I get the laughs, swearing, 'I've had a negative test'.
Thankfully the people who/I have booked are patient, polite, and pleasant.
