I often go to a small restaurant to have pickled fish with酸菜

I often go to a small restaurant to have pickled fish with酸菜. Their sign says "fresh fish killed on demand, around 4 jin, 99 yuan per fish," and the restaurant is simply named "Pickled Fish Restaurant." Every time we visit, we order a whole fish and two bowls of rice, which my husband and I always finish completely. We always feel that a 4-jin fish isn't very much - it disappears after just two bowls of rice. Yesterday, I bought a fresh fish from the market, exactly 4 jin, and had the vendor slice it for me. Following an online video tutorial, I made pickled fish at home, and it tasted almost the same as the restaurant's. However, I felt the quantity was much more than what we get in the restaurant. My husband and I could only eat half of it, and we'll need two meals to finish this fish. In other words, I was surprised that the fish I cooked at home was significantly more substantial than the one we eat at the restaurant. As ordinary people, we can tell the weight difference. Why is there such a discrepancy? This made me realize that the so-called 4-jin fish sold in restaurants probably contains a lot of "water." While they claim it's a whole fish, in my opinion, it might just be the tip of the iceberg. The other half of the fish might have joined the army of overseas returnees in the food delivery industry. Watching those delivery orders fly around like snowflakes left me with mixed feelings. Every time I go, the boss dramatically kills the fish in front of me before taking it into the kitchen, like an impromptu stage play. If I didn't follow him in, would the show be even more interesting? In essence, everyone loves the fresh fish taste, but freshness should come with genuine quality - quantity matters most. This incident serves as a wake-up call. Eating out is not just about taste enjoyment but also a test of trust in the ingredients. While we may not have Sun Wukong's piercing eyes, we should at least have some basic wisdom to tell真假. Next time when eating pickled fish, we might as well be more vigilant - perhaps we'll discover a new continent. What do you think? Are there any similar experiences to share, or any thoughts on restaurant portion sizes? Feel free to discuss in the comments section.
