Final answer:
The number of pumps in a large milkshake varies by establishment and machinery, but a typical 11 oz flavored milkshake may require 2 to 4 pumps of syrup or flavorings.
Step-by-step explanation:
The specific number of pumps or swipes in a large milkshake can vary depending on the establishment's recipe or the machinery used. However, given that we're examining an 11 oz milkshake, and referring to typical servings for flavored milkshakes or similar beverages, one can estimate that the number of pumps for syrups or flavorings usually ranges from 2 to 4 to achieve the desired taste and consistency.
The exact number of pumps for a chocolate or strawberry milkshake would likely be specified by the establishment's standard recipe to ensure consistency across servings. It is also essential to consider that the measurement for syrups and flavorings might be standardized across food and beverage operations, but still, they might slightly differ because of different brands' concentrations or the preferences of the local consumer base.
