Final answer:
No, tap water is not automatically served with lemon. The taste of tap water can vary depending on the location and filters can improve its taste and remove impurities.
Step-by-step explanation:
No, tap water is not automatically served with lemon. Tap water is simply water that comes from a faucet or tap. It is usually sourced from a municipal water supply and goes through a treatment process to make it safe for drinking. Lemon is not typically added to tap water unless someone specifically requests it or if it is being served in a restaurant or café that offers flavored water options.
It's important to note that the taste and quality of tap water can vary depending on the location. In some areas, trace-level concentrations of contaminants can render unfiltered tap water unsafe for drinking and cooking. Water filters can reduce the concentration of solutes in tap water, improving its taste and removing impurities.
Ultimately, whether or not lemon is served with tap water is a matter of personal preference and the establishment's offerings.
