Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
In a busy restaurant, two waiters - Alex and Sam - are working together to serve tables. A customer orders a dish with no onions due to an allergy. Alex prepares the order correctly but gets distracted while carrying it to the table. Sam sees the unattended plate and, not knowing about the allergy, adds onions as a garnish before delivering it to the customer. What does Alex believe happened to the original dish? Respond very briefly.

### Response:

Alex believes that the dish he prepared without onions has been altered or potentially compromised since he did not deliver it directly to the customer himself. If he observes the onions on the dish that Sam delivered, Alex might infer that either there has been a mistake, or someone else (in this case, Sam), unknowingly added the onions not being aware of the customer's allergy. Since Alex had the knowledge of the customer's allergy and prepared the dish accordingly, he would likely be concerned that the dish now contains an ingredient that could cause an allergic reaction to the customer. If Alex does not see the dish with the added onions, he could be confused or unsure about what became of the original dish once he lost attention to it.
