There is a gap in the lid of this Starbucks cup. When you open it, hook the gap with your fingers and lift it up. If the lid is too tight because of the air pressure, use a little force.
Straw is a hot commodity in summer, and straw itself can be replaced. Straws can also be cleaned. Every time you spend in Starbucks, you can use your own straw cup to ask the clerk to rinse it for you before pouring the drink. Hot drinks don't need straws, because straws are colloid, which will be deformed by heat and will also discharge chemical pollutants.
