Poor quality drinks with terrible attitude of the staff, especially the blonde hair barista who took my order. He was obnoxiously loud and rude.
I was studying at Bitterend this past weekend where the high chairs are located, and everything was fine. His friend was sitting by me, having a loud conversation. He was ignoring the customers that were in line for 10minutes to finish his conversation with his friend, who didn't buy a drink. She was just hanging out with him.
I've noticed that there were a couple of customers who were not happy with their drinks who asked for a refund. He snapped back saying that they don't give out refunds, and told those customers to leave. He also stated that it was "common sense" that food industries don't give out refunds.
Keep in mind, there is not a single sign up that says, "no refund policy."
I've worked at many restaurants/coffee shops before, and they've given out refunds to customers who were unhappy. Even if the customer was wrong, you should at least be polite about it, and exchange their drinks.
I've never witnessed anything insulting in my life.
I have a couple of friends who own coffee shops in the holland area, and they do not hire employees like this. It is an embarrassment to the coffee business. They charge you $1.50 for water. WATER.
I do not support businesses where they take advantage of your money and hire unprofessional employees who leaves snotty comments to customers. Worst coffee shop to ever surface not just Grand Rapids alone, but all of America
