That’s ok we hen you are still building a round but not an option when you are full as no spare time to do it , we just dump and replace them with better paying jobs , but to be fair rarely get this now as customers are told before we take them in how we work .
? I've seldom got slack either but never turn away occasional customers especially if they fit in on a flexible basis and pay a premium.
for OP Always be polite when out and about, you can dump irksome customers nicely. Remember if you are rude or curt they will make a point of bad mouthing you to hundreds of potential customers in your area or leave you negative feedback on the varied media.
