You said it in the last line. That's how I know you will do well.
My lhbs is like walking into a large pantry, they always have fresh ingredients. and friendly service, No matter how busy they are doing store work, they greet every person coming in through the usually open door, If they know their name or their business they will ask about it etc.
They also have space outside where they grow hops and have raised garden beds. In addition to teaching free brewing and wine and cheese making classes, they also teach classes on gardening, composting, canning, preserves making etc. And showing how to tie said techniques into your home brewery. Ie cheese pairing etc
I keep a large inventory of ingredients and supplies, so I don't always have a big order when I go in. But they always thank me for my business whether I'm spending 200 or 2 bucks. They make you feel like family and that will ALWAYS earn my repeat business.
