SCENARIO You are working at this convention and your feet are in excruciating pain, after 8 hours standing in those tight shoes. You finally can take the place of a colleague seated at a desk, always welcoming customers. The camera shows your legs and your feet from the left side, as below. Sometimes you have to stand and to left to follow a customer, sometimes you stand but you stay close to the table like talking to the customer. You often complain saying as usual “oh my feet”, “oh my poor feet” and “my feet are killllling me”
