"I have been a vegetarian for over eight years and have never eaten any meat during that time. Unfortunately, due to a careless employee at Shake Shack, I ended up accidentally consuming a bite of beef. I ordered the veggie black bean burger and became physically ill as a result. I am very disappointed and will not be returning to Shake Shack, especially for those with dietary restrictions. The lack of care on their part was unacceptable. Despite reaching out to them, I received a refund and a $15 voucher, which does not make up for the betrayal of my vegetarian lifestyle. I will not be going back to Shake Shack, as my health and values are more important to me than a simple apology."
