If I have to wait more than 25 minutes to be served when there is only 2 other customers in store, I cannot wait around. I also run a small business and if my staff kept people waiting for service like this, they won't be working for us. Acknowledge the customer and let them know how long it will be before they can assist you.
There are other options and best I go elsewhere.
Very polite people, was a pleasure to walk in to their shop. I don't know much about batteries but I got them to test my car battery and they were very helpful in getting me sorted and back on the road with a new battery. Thank you <3
