No, It is Cluster Sampling

Step-by-step explanation:

Simple Random Sampling is the sampling when samples are chosen randomly, where each unit has an equal chance of being selected in a sample.

If the population is divided into a different group called cluster and clusters are selected as a sample then it is Cluster Sampling.

If the manager checks many items randomly on any day of the week at any time and selection of each unit has an equal chance then only it will be Simple Random Sampling.
