H‑E‑B — heb better burger leaf lettuce

Good evening to whom it may concern,
My mom and I were enjoying some sandwiches tonight when we discovered (for the second time) some brown spots on our lettuce. This could be mud or feces, nevertheless it wastes the product and also our money when we have to throw away produce because we're unaware of what exactly is stuck on the product. This would be of no concern if this product didn't claim to be "Washed, Hand Trimmed and Ready for Use". This product was also being consumed two days before the expiration date. I love HEB, and would like to continue buying and consuming your products only if I were to be receiving what I paid for initially. Thank you for your time,
