Customer expectations are increasingly influenced by the culture of instantaneousness, custom customization and the "price" laws that characterize the current market. Although it is understandable that customers want quick services e customization, it is important to consider the limitations of machine shops.

1. Very fast delivery times: the request for extremely short delivery times can put a strain on the production capacity of small and medium-sized workshops. The production of parts requires time and trained personnel to ensure the quality of the work performed. Pushing companies to excessively reduce delivery times could lead to a decrease in the quality of the product and the service offered.
2. Immediate estimates: Formulating a quote requires a thorough analysis of project requirements, required materials, and available resources. A request for an immediate estimate could force the workshop to make approximate estimates, which could lead to budget problems or to work that does not conform to the expectations of the customer who requests specific processes from metalworking companies. 
3. Custom pieces: Customizing parts is a legitimate customer expectation, but it can bring additional challenges for metal shops. Designing and manufacturing custom parts takes time and specialized skills. Additionally, there may be difficulties obtaining the specific materials required or making complex parts that require specialized machinery.
